Comments: Always on the lookout for soft polys so tried this one. My hybrid setup in my Head Prestige Pro is Yonex Poly Tour Pro 17g mains and Technifibre NRG2 17ga crosses at 54 lbs. I swapped the Cyber Blue in on the mains for a few sets. Based on my experience, can't recommend it over the Yonex PTP. Comfort was OK, less predictable on off-center hits, sweet spot hits were really dead without that crucial bit of feel I get from the Yonex string. The killer was much less bite and spin compared to PTP; real trouble keeping serves and forehands under control. Seems others have had better experiences with it but it doesn't work for me. 4.5 USTA, big serve and forehand.

Comments: It's probably the softest poly string with excellent tension stability with some power and feel. I hybrid this on my mains and cross it with Isospeed Control classic 16 gauge. It's arm friendly and low cost with high performance.
From:Jake, 2/9/18

Comments: Great string. Very soft and arm friendly. Spin amount is average. This plays similar to Babolat Pro Hurricane in my opinion.
From:RBC, 4/16

Comments: Terrific string, just what I needed to tame the power of my racquet and also provide great feel and control, excellent tension maintenance and a comfortable impact. I didn't think I would find anything I prefer over Silverstring but this is the one.

Comments: I string my own racquets and try a variety of strings. I used Topspin Cyber Blue in my Head IG Radical Pro at 58 lbs. There was no break-in period to get used to it. This string worked seamlessly out of the gate. It does have a softer feel than a RPM blast (my usual go to string 17 ga) but I didn't notice any crazy amount of topspin compared to other "textured" polys. It had good control for volley's as well. I don't get caught up in the price factor as a real criteria for swaying toward a sting or not. I just really liked how this string played in my racket and for my game.

Comments: Cyber Blue is excellent! According to USRSA, Cyber Blue is one of the softest polys on the market along with Babolat Pro Hurricane, Signum Pro Poly Plasma, Tecnifibre X Code, Kirschbaume Pro Line II, Volkl Cyclone, etc. But Cyber Blue is the best in tension retention among them. Highly recommended to hard topspinners and the chronic string breakers who don't like the harshness of polys. I purchased a reel. Price is great too.

Comments: A good string for topspin and and good control.
From:Jatin, 7/13

Comments: After reading many reviews, I decided to try this one. This is a soft poly sting, with good control, crisp feel, and some spin. Also this is the first string that made me feel the ball sitting on the stringbed before launch. I'm ok with this string. I think this one is good for a hybrid, and the price is nice. I strung a full bed of it on a Volkl PB 10 at 40 lbs and Organic V1 at 45 lbs.
From:Tong, 8/12

Comments: I just started using this string on the mains with NRG2 on the crosses. It gives you tons of spin and control. The NRG2 multi's make it very comfortable but it does make my first serve fly a little bit long, just like Kevin's comment from 3/10. My first serve is a kick serve. I think that it is because the multi pockets the ball more. I have experimented with slightly stiffer syn gut's in the crosses with the cyber blue in the mains and it definitely makes the serves go curve in with more pace than with the multi. Overall, this is an excellent softer poly with great spin and control. The tension maintenance seems pretty good too. I may try the 1.20 when this reel runs out!

Comments: Don't know if I should post the comment here as they are meant for Cyber Black instead of Blue. Anyway, the Black was strung on my MGR OS at 55lbs and it's magic. At first, you can't really tell but after two sessions, the strings are amazing!! If you hit it correctly, you can feel the ball sitting into the stringbed and waiting for your command. it's fantastic! Anyone who can get their hands on the Black should try it.
From:Ben, Singapore. 6/10

Comments: I'm trying out this string in a hybrid, with multifilament crosses, 55/58 on a 95 sq". It's a very comfortable hit with good power. Unfortunately, in this setup, my serve often goes long and my deep volleys don't have the control I'm used to with an all multi setup. Looking at the other reviews, I'd like to try it on the whole stringbed. It feels great, looks great, and if it will give me bite and spin, it would work out really well.

Comments: I tried this string after one of my friends recommended it. From the moment I stared playing with it I felt that I got much more topspin and control. No matter how high you hit the ball it will curve in.
From:Anson, California 02/10

Comments: Fine quality strings. My only complaint is that they are a little too muted for my taste. I like more of a raw banging sound when I rip into a forehand. Don't worry about arm problems with this one--it is extremely soft, probably too soft for me. Holds tension well and you get a very predictable and reliable "crispy" response. Good especially for serve&volley or all-court type players. Go with Cyberflash if you are a baseline basher.
From:Ron, Toronto, Ontario, Canada 12/09

Comments: I used to be a strong proponent of this string. Something has changed and it now breaks easily. Not worth it since durability has decreased.
From:Julio, Miami, FL 09/09

Comments: This string plays so well at a very, very lose tension on a smaller head racquet. I play with an nCode Tour 90. The quick swing, and smaller sweet spot balances out with the loose strings to produce a machine. It hits fast, powerful but with control and LOTS of spin. I highly recommend this string for anyone looking for power and spin. Be warned that although I said it gives control, it's better for a K90, N90, PS90 or anything from 90-93 inches with a heavier head. Everyone to own though right. With a low tension you also make the strings last longer, allowing for flexibility. By the way, an underrated aspect of this string is the way it can hold its pattern and set up without flailing around too much.
From:Justin, Brisbane, QLD, Australia. 1/09

Comments: Awesome string. I actually hybrid this with Luxilon Big Banger Alu Power on main. Luxilon is a very stiff string, but with Topspin Cyber Blue on cross, my Prince Speedport tour was absolutely amazing. The playability is incredible. Control is very good. I recommend to heavy hitters.

Comments: Very solid string. Good spin and control. Reasonable power. Found it easy to place volleys and very comfortable to hit groundstrokes. Slightly less spin than SPPP or Cyber Flash, but very comfortable on the arm. I get about 15-20 hours on a set of strings, mostly playing doubles. I'm a 4.5 player using a K-Factor 95 strung at 55 pounds. I've also tried these other strings - SPPP, Topspin Cyber Flash, and Tecnifibre Pro Line II, Pro RedCode, and NRG 2. Cyber Blue is the best overall string that I've tried. My next favorite string is SPPP which has SLIGHTLY more power and spin, but is a little tougher on the arm.

Comments: Great string awesome pop on serves and groundstrokes.
From:Kurtis, California. 11/08

Comments: Have tried many poly strings just trying to see what all the hype is about them, started playing tennis in the early 60�s and became accustomed to natural gut strings, nothing else would do. Cyber Power, or Cyber Blue is actually the first poly string I have tried with possibilities, Natural gut is still the best for me, but I will give Cyber Blue a chance because I did in fact like the way this string feels. Other poly strings have pretty much turned me off, cyber blue seems to have more power with less wear and tear on the arm than other poly's 3.5 to 4.0 all court player.
From:Rudy, Glenwood, NM, USA, 10/08

Comments: I Just tried full Cyber Blue 17 this past weekend, and liked it very much. Had been playing full Cyberflash 17 at 58 lbs in a 107 sq in head without any elbow problems, and also liked that a lot. Went with 60 lbs on the Cyber Blue (because it's supposed to be a bit softer than the Cyberflash). Seemed to me that it was a little livelier than the Cyberflash, but not uncontrollably so. Like the Cyberflash, Cyber Blue doesn't move around. So far, so good.
From:Rich, Massapequa, NY, USA. 9/08

Comments: Just changed to these strings and absolutely love them! I have them strung up at 54 on my FXP Prestige mids. Wow what a combination. I feel that these are perfect for tight patterned, low powered raquets.
From:Matt, South africa. 7/08

Comments: I've been using these strings for about a year now. These strings are as good as many of the Luxilon without the price tag. I use these strings on the mains with Wilson Sensation 16 gauge and it feels awesome. Not only that, but it only costs me like $7 to string with this combo.

Comments: This string is just too easy. I actually hybrid this with Babolat Pro Hurricane and, o baby, it's too easy. Wonderful, truly wonderful.
From:Steve, Wisconsin, USA. 6/08

Comments: This is a tough string. I thought it felt OK but had a hard time with my slice. After 20 minute felt some elbow tightness then some elbow and shoulder soreness. Compared it with Kirschbaum Pro Line II and the Pro Line II puts this string to shame. There is more feel, pop and playability. I would not recommend. I'm an ex-collegeplayer/open player strung at 52lbs. on my Yonex RDS 500.
From:B-UNIT, CHULA, CA, USA. 5/08

Comments: Based on Kevin's comments I bought these strings. Thanks, Kevin! This is the best poly/co-poly string I have ever tried, and I've tried them all. Lots of juice and so far absolutely no arm or wrist problems. That is saying a lot as I am a 60-year-old 4.5 player. I've never served better with power and control. Finally, I may now be able to move away from hybrids, and these strings are bargain priced, especially in a reel, compared to other poly/co-polys. I string my Pure Drive at 55 lbs. with Cyber Power. Perfect.
From:Gerry, Bradenton, Fl, USA. 3/08

Comments: I had read that these strings felt more like synthetic gut than any other poly on the market. Not only did they feel like synth gut, but they also performed a bit like synthetic gut. The typical poly spin potential didn't seem to be there, and control was a bit lacking, but it was a very comfortable and powerful string. I'm sure there are legions of players out there who would benefit from this soft, durable poly.

Comments: Wow what a great string! I have been heistant on using poly strings since I had previously experienced some tenderness in my wrist/elbow with other poly strings, but not the case with the CP. I used CP mains crossed with Pro Supex Max Touch, and it was wonderful!! Control, power and tons of spin and best of all -- no soreness at all! I was really impressed. If you're considering a soft poly with some pop, yet control, give these a shot. Strung on Diablo MP at CP 52/MT 55.
