I am still having my cross strings move too much and my balls still fly out too much for my liking, so I decided to try POLY and see if it helps. I debated which to try, but the Kirchbaum prices were tough to argue with so I am trying both Touch Turbo and Competition. I would love to hybrid them with natural gut, but I dont have that kind of bling-bling to spend on string so I will either do 1-piece stringing all Poly, or hybrid with Gosen JC syn gut 17.... I would have tried Babolat Hurricane too, but it was backordered... C'mon TW, it is supposed to be a WAREHOUSE... keep more stuff in stock!!! I also was intrigued by the Unique ALU-copy, but I wanted to spend around $8 and it is still too much. sKrew luxilon, I am not paying 2x for the name... can't be that different can it? I will be sure to post how the Poly-test goes from my normal string Technifibre NRG2 18g.
