Racket used: Volkl Catapult 10 I have tried many strings with Cat 10 and eventually found the ideal one which was RIP Control 17 at 62/62. It seems to reduce the "catapulting" to reasonable level. But RIP Control doesn't last very long, so I always tried to move to something more durable. Have tried Pro Hurricane 17 at 58/58 and it was the best so far, but concerns over my GE pushed me to search further. I have strung Cat 10 with Signum Plasma 1.18 at 57/57, following the recommendation on the pack about 10% drop from my normal tension, even made it higher by 1 lbs. Disaster. Trampoline is huge and even spin can't force the ball into the court. The string is quite soft and Pro Hurricane is better at spin generation. So my conclusion is not to drop tension at all or drop it just a little bit. They say, reduce tension by 10% because the string doesn't lose tension. Now I am thinking - good, I will play like with freshly strung racket every day, but why do I have to reduce tension originally? I am not giving up, next will be Sig Plasma in Cat 10 at 60/60 or even 62/62. So, it's not a bad string if you string at right tension. It's softer than Hurricane, almost as good at spin. Will see about durability and tension maintanance. Word of caution to who doesn't know what Cat 10 is. This racket has "catapult" in it, very distinct feel, very distinct play from any racket. So, Sig Plasma at 57/57 might be pretty good in other racket.
