I'm a 41 year old 130lb 4.0 woman (I'm a 4.5 if you go by the USTA videos on YouTube but i play with 4.0 women) and i did not like the Clash with a poly. I have the Clash 100 with lead tape at 10 and 2. I was using NXT 17 multifilament strung at 50 lbs and wasn't satisfied with the spin enough to continue paying $20 for one string set. The power and control were good. But the NXT started fraying badly and the durability isn't great and I wanted to try something less expensive with more spin. I had Volkl Cyclone 16 black strung at 46lbs. It was horrible. To be fair, I probably should've done 17 gauge. I played with it for an hour and it made both of my elbows hurt. I immediately switched back to my other Clash with NXT to save my elbows. Low power, which i expected, but no improvement in spin, and my technique is good. Had those cut out and now I've played an hour with Technifibre Multifeel 17 black multifilament strung at 47 lbs, and the spin and control are good for me. Less power than NXT, but with the increased spin, I feel better generating my own power. Almost as comfortable as NXT but half the price. Hopefully it will be more durable. Just sharing in case this is useful for anyone else.
