Comments: Trying out this string from using regular Cyclone 16 Black, recovering from tennis elbow. Neither causes pain, but being cautious by using a softer string. Generally both versions are more springy than your average pure poly (used Gamma Poly Z in the past). Definitely more pocketing and spin than plain poly. Biggest knock on both Cyclones is tension drop/maintenance, even when giving 30 seconds pulling tension on a stringer so tension weight stabilizes. Having a final target tension of 52 lbs, I decided to string initially at 60 lbs. After my first 2 hour session, the tension dropped to 55 lbs. After my second 2 hour session, the tension dropped to 52 lbs. After my third 2 hour session, the tension stayed the same at 52 lbs. I used the Racquet Tune app to check tensions. I made sure to get my first reading right after a fresh stringing for accuracy. Hopefully this info is valuable for those who want to get more longevity and tension maintenance from this string and others without cutting them out prematurely. Overall, I'm happy with this string. Need to accentuate the loop on forehand to keep the ball in at 52 lbs, so will work on my technique. At 55 lbs, the ball landed 2-3 ft from the baseline. At 60 lbs, the ball was landing at the service line.

Comments: This is my first adventure into poly strings. Usually I use a multifilament. Not quite the power loss that I was expecting but my confidence grew after about 20 minutes of hitting. My accuracy was much better and net play was more crisp. Biggest difference is to make sure that you follow through with your swing to get the depth and control I was accustomed to with the multifilament. Not a bad way to enter the poly universe!

Comments: Unbelievably comfortable, spin-friendly, reasonably priced, and a durable poly. I strung it in my Babolat Pure Strike at 52 lbs and played 7 matches in a doubles tournament (12 sets) and it felt great! Had massive bite on the ball, didn't change in feel, and was surprisingly comfortable. I've officially found my favorite poly. I can see why the Tennis Warehouse playtesters love this string. Thanks Volkl!

Comments: I had these in the mains with Gosen multi cx or something in the cross. Had it in two racquets, both lasted a good amount of time and the setup worked very well. Not a soft poly but not harsh either. Good spin and power. I'm probably going to try them again. I strung it lower, so say 50-60 range, I did it at 48 lbs on one at 52 lbs on the other.

Comments: The string plays well for one training session. But after 2 hours of play it has lost 6 lbs. Not very useful as a stand-alone poly. But it might work well in a hybrid.
