What I have tried
I originally strung mine with Signum Pro Poly 58 pounds. 18 gauge. I really liked it. The first set lasted a few months and was still playing pretty well.
Those busted so I just tried Luxilon Floro same tension. I am not really liking it.
I can still serve well, it just doesnt feel like the same racquet.
I think I am going to try a multifilament, maybe x one biphase.
