Comments: Cyber Flash is a decent polyester option. I tried it at a low tension as most polyesters work at low tension, 44 to 48 pounds, and it got better the lower it was. Soft, good spin and touch, and looks good in any racquet.

Comments: Listen to John from Portland (5/10) and Jack from Lynchburg (2/11). They must have changed the string. It is much stiffer and does hold tension. It also low powered and the spin production is average, not great. I prefer a softer poly that is higher powered n with more spin production, and that's why I won't come back to Cyber Flash again.

Comments: I was looking forward to using this string but to my disappointment it did not perform to my liking. It was too stiff and low powered. Yes, this gave me excellent control, but I would really prefer a string that is softer and with more power. I would also like more spin from my strings. The spin potential is decent from this string, but it can improve with other strings. I strung hybrid with Forten Sweet in the crosses at 57 lbs on a Head Prestige Mid. Perhaps I should string lower with the half set I have left.

Comments: I has been testing strings all summer and I came upon Topspin Cyber Flash and tried it. First off, I was impressed with the solid feel the string had. The spin was good but not amazing and power was average for a poly. It is ok to use but not one of my top strings to use. I like Kirschbaum Pro Line 2, Luxilon Big Hitter Blue Rough, and Tecnifibre Black Code better. To me, they all had a better feel and I was able to get more spin and power with these. I would give it a 7.5/10, because I am able to play with it but it is not the best for my game.
From:Chris, 10/11

Comments: Agree with John from Portland. I just started using my most recent reel and it is definitely stiffer and has a smoother surface. The spin is pretty good so far, but it is lower powered than before and seems to maintain tension a little bit better. I would agree that the company seems to have changed the formulation...since I have a whole reel, I'm going to have a lot of time to get used to it :)
From:Jack, Lynchburg, VA, USA, 02/11

Comments: After reading so much positive feedback from the forum, decided to try it out. This string does not feel anything like Lux Alu Power. It's much softer in comparison. This string is more comparable to Prince Tour. The 16G & 17G have a huge difference in stiffness for me. This string is good for anybody who wants a dampened feel.
From:Jack, MD, USA, 01/11

Comments: This string is wire-like and it doesn't pocket very well either. I hybrid'd this with natural gut in the mains: 57/55 gut/cyberflash. It was no where near Luxilon alu's power and I started to develop major aches after a hr session. I don't recommend this, especially with gut at all, even if its in the mains. However, I shall try decreasing the next set with cyberflash at 52 and that might help but I doubt much.
From:Adrian, Altdorf, Uri, Switzerland. 07/10

Comments: The company has changed the formulation of the string without informing us. And that created a lot of confusion/headache for me. Although it maintains tension better, it lacks power and is much stiffer-totally different string. I had to lower the tension at least 8 pounds. Even that it still doesn't feel the same as before. It's too bad that they discontinued the previous cyber flash.
From:John, Portland OR, usa. 5/10

Comments: This is the best poly I've used and I've tried quite a few. I like this better than the Luxilon ALU Rough, the ALU has too much power thus harder to control. Cyber Flash 17 is a very well balanced string in terms of feel, control, power, comfort and spin potential. I've hit some wicked shots with this string and I've noticed how much of a difference the way the ball is flying through the air. The only negative I have about this string is its durability. I string at 55lbs full poly and my first setup broke in 3 or 4 days of 2 hours worth of hitting per day. I am 4 hours into my second setup and I can see the notching developing to halfway already. Is anyone else having this same problem? Love the way it plays but durability is an issue.
From:Laney Tennis, Oakland, CA, U.S.A. 03/10

Comments: Strung @ 55lbs on Pure Drive Roddick. It's a bit springy. I noticed a bit more topspin but it took away from the drive that I liked so the balls I hit didn't go as deep. Very easy to string though and I feel it's pretty soft for a poly.
From:Vincent, CA, USA. 7/09

Comments: This is one of the best strings that I have used. The hybrid really works, and from the comments it is one of the best hybrids. I won a lot matches after switching to this string as a hybrid. When I used it for the whole frame I was missing some shots out, it was great for power, but not control. when I switched it to a hybrid I won a tournament! I really recommend this string.
From:Janae, USA. 04/09

Comments: WOW that's all I have to say. My friends and I love this string, so much like the Luxilon and easier in the pocket. The only set back we are breaking the strings within a week but that's ok we were doing it with ALU Power also but I would rather order 100 reels with the price of Luxilon.
From:Greg, Miami, FL., USA. 4/09

Comments: Finally strung my Wilson Ncode NTour with my new Silent Partner Swing Stringer and absolutely love the control. I took the advice of another post and bought some Gosen Sheep Micro 17 for the crosses, which worked out really well. If you're doing your own stringing job do be careful when pulling because if you pull too fast it will break in no time. With that said it probably took me a good half-hour to string the mains. But it was well worth it. Last night I played with someone who usually beats me, but it was a whole different ball game. 6-2 to me.
From:Ron, Los Angeles, CA. 4/09

Comments: My new favorite string. It's pretty unanimous what everyone says here. Good tension stability, plays like ALU Power with a little less control but better comfort. The cost per reel, though, which makes this string the best value poly out there IMO. Crossed with PSGD 17 in a Wilson K Six-One 95 18x20, 60 main, 62 cross.
From:Mo, Virginia Beach, VA, USA. 2/09

Comments: I heard from a lot of people that this is just like ALU Power. Well, here is my comparison to it.
Better Spin - CF
better power - ALU
better tension CF
better control - Both
Better durability- CF
Better Comfort - CF
better Price - Cf
It's better than alu in most aspects but power.
From:ANON, NORCAL. 2/09

Comments: Just some advice. It might be best to stay away from a whole Cyber Flash string job. Try it as a hybrid. As other mentioned try it at mid-tension but even lower to start out with would be a good idea. I get my racquets at +2/3 55 but with CF maybe -1 to 3 lbs.
From:lk. 2/09

Comments: First time I tried these strings it was strung too high. It was stiff as a board but after a few months when the strings started loosening up, these strings were amazing. String this in the mid-low mid range. These strings literally play like a "Baby ALU Power" it has good spin, great durability, awesome tension maintenance, and minimal string movement. Great polys at an incredible value.
From:Andrew, Sunnyvale, CA, USA. 1/09

Comments: I've been experimenting with different strings, and Cyberflash 17 is the best fit I've found. Excellent control, toned down a hot sweet-spot on my racquet, never moves. I hit with a lot of spin and find string movement very annoying. Compared to Prince Lightning XX 17 and Gosen OG JC, much better control and spin, less power. So far, playing once a week, tension and pop seem to be holding after a month. I am guessing the amount of court time has more to do with the deadening of this string than absolute time. It will be depressing to cut the string out before it breaks, but I guess that's the way it works with newer poly.
From:Kurt, Colorado Springs, CO, USA. 11/08

Comments: This string is very good value for money, and is almost as good as Luxilon ALU Power. I compared them side by side and ALU feels a bit more elastic and gives a better feel and power. Also, hours before Topspin Cyberflash broke on my racquet, it was pretty dead, not elastic and even though I swing hard, the ball wasn't moving. For the Luxilon though, it has power right up till it breaks. Given the price difference, I think I'll compare the 18 gauge version of Topspin Cyberflash and compare that side by side against Luxilon.
From:Derek, San Francisco, CA. 11/08

Comments: I tried these strings out when I was finally tired of realigning my strings after every point. After switching to these, I have never ever, not once, had to fix the string bed. These strings are now my favorite.
From:Luke. 9/08

Comments: Wow, such great string. I have it on my Wilson k6.1 95 on mains, cross with Tecnifibre synthetic gut 17 @ 55lbs. The result is staggering! Such great spin that I haven't encountered with any of my previous strings. My flat shots, just land few inches within the baseline. Incredible control and spin. The power is great, too. The tension maintenance is much better than other poly like Signum Pro Poly Plasma. I haven't used such great poly in a while except, well, the great Luxilon Alu Power. I am gonna stick with it for a while!
From:Anakin, San Francisco, CA. 5/08

Comments: Great string but little to plasticky. It breaks within one hour.
From:Ben, Chino, CA, USA. 3/08

Comments: Decent string, tons of spin, a little to springy, but I could probably fix that by having a higher tension. Pretty comfortable, not great power but good enough. Overall it about fits the price, if anything the price is a little high. I was a little disappointed.
From:Andrew, Eustis, FL, USA. 2/08

Comments: This is a great all-around string at a decent price. Durability, power, control, feel and tension maintenance are all on the high end without the horrible price of other top end strings. I would definitely recommend trying this string if you haven't.
From:T, SD, CA, USA. 2/08

Comments: Very good string. I have it on a T-Fight 335 16x20 @ 56lb and it performs excellently so far. A little bit harsher on my forearm than the 17L version and the 17L of SPPP, but durability seems to have increased a lot. I rank it second only to the 17L version which has the best ball bite/power/control/feel combination I have ever seen, but the durability trade off is worth it when you play a lot. Give it a try and account for the fact you have to DROP the tension if you are switching from multifilaments by at least 5%.
From:Bobby, Stamford, CT, USA. 6/07

Comments: All I can say is WOW! By replacing SM 17 in the mains I can finally take huge cuts at the ball and still have everything fall in the court. And there is no string movement which is greatly extending the life of the string bed. I'm finding I can swing out harder on groundstrokes with more control. However have lost a good bit of touch on volleys, but found more pop. Serves/overheads are insanely powerful and generate a great explosive sound. Net result to date is greatly improved control when ripping groundstrokes. Some loss of touch on serves and volleys but improved power. More spin on all shots and comfort almost the same level as an all Gosen SM string bed. My regular crew is commenting constantly on my improved shot consistency and reduced unforced errors. If you like to really rip the ball, but struggle with control, CF is a must try.
From:Netman, Southeastern USA. 5/07

Comments: The BEST string EVER! I've used Luxilon Big Banger / Wilson NXT for a while, and after stringing every 2 weeks, those combo was getting expensive, so I was trying to find a replacement for that combo. Now, I am using Top Spin Cyber Flash 17 and Wilson Extreme Syn Gut 16 on my K Factor 90. The Cyber Flash has more power and crisper than the Luxilon for cheaper price. The only downside is the Luxilon has more control, however the tour 90 racquet has great control. Recommended for someone looking for budget poly, crisp and more power poly. Arm friendly too by the way
From:L, Newport Beach, CA, USA. 5/07

Comments: In my opinion, the best polyester out there. Great ball pocketing for a polyester, and superb control.
From:Jay, 04/07

Comments: I am a 4.0 all rounder. I tried 1 set of string. This is the second poly string for me next to Luxilon Big Banger Ace. This string feels great. After about 10 hours of play test, I feel a little loss of tension. But this keeps still good feeling. When it comes to the performance, this comes with good power, great feel and decent control. Besides, no string movement is detected. If you buy a reel of this, you get through definitely "THE BEST" performance/price rate in the market.
From:Sean, Los Angeles, CA, USA. 4/07

Comments: Easy string and virtually no string movement during play good spin and power and crisp on the volleys, I would rate this string very close to the Luxilon ALU power but a lot cheaper, I pre-stretched the string and found hardly any tension loss after 3 hours of play. for the price a highly recommended string.
From:Michael, Earlville QLD, Australia. 4/07

Comments: Best value on the market. Tons of spin, last forever, and doesn't move. I was using TNT before trying this and liked it for the first few hours, but it soon lost a lot of tension. This is much better. I seem to have much more control.
From:WB, Charleston, SC, USA. 1/07

Comments: Awesome! This string is incredible. I used crossfire before I tried it. The former was like a steel bed, and did not offer as much spin as cyberflash. In fact, the spin was so pronounced, that it took my game to another level.
From:Kaojun, Singapore. 11/06

Comments: This is the first poly I've played with, and I love it. I strung it 4 lbs looser than my usual synthetic tension (having heard a lot of comments about the need to string poly a little looser than synthetic), and I've very happy with the results. No discomfort, excellent control, and excellent 'bite' on the ball, resulting in great spin.
From:Rich, Massapequa, NY, USA. 11/06

Comments: Overall it's a great string. It's almost like Alu Power but a lot softer and cheaper. It's a great string for the price, but the only thing I don't like is the durability. I like to rip my shots so these strings only last me 4-5 days. Other than that, I recommend these to everyone.
From:Steve, Tustin, CA, USA. 10/06

Comments: Best polyester on the market. I was very upset when I had to stop using Luxilon ALU Power Rough due to golf & tennis elbow. I've tried many polyesters, but none came close to ALU until I tried Cyberflash 1.25. This string is the most powerful poly that I have tried and way more comfortable than ALU.
