i've used sppp, luxilons, bunch of multis like nxt, various synth guts, various nat guts, and my favorite out of everything i've tried was pro supex big ace 1.22 strung at 59 lbs in a n6.1 16x18 95 - but reading reviews some people say it lacks power. i hit quite powerfully so i'm not sure that even if does lack power comparatively it affects my ability to hit winners, but i'm interested in some input - compares to the other poly's i've tried it definitely doesn't seem to lack power to me, but i've only tried 3 other polys, so i don't have much a frame of reference - although it seems the consensus on big ace is that it's great, which i definitely agree on and will probably continue using it for a while longer unless there's a poly that lasts as long as big ace does without going dead and isn't stiff as a board even at the relatively high tension of 59... eh? people say kirschlbaum pro line 2 is good? kirschlbaum p2? technifibre black?
