i know this has been covered a million times, but we all experiment and try new set-ups. right now i have two in my k90s: #1: luxilon 17g mains, NXT 16g crosses @ 49/51 #2: NXT 16g mains, luxilon 17g crosses @ 51/49 it's my first time trying hybrids and i have to say that (to my surprise) the first set-up is much much better than the second. the first one has tons of spin, the perfect amount of power, and plenty of control. the second set-up has more power, but much less spin...the ball just rockets. (note: everything above that tension has been like a board to me...not enough power and dead feeling. also of note: i'm a baseliner who hits hard and throough the ball with moderate of topspin.) even though i love the first set-up, the NXTs are being sliced by the lux, so i need to improve that situation somehow. i don't want to lose the extra power by going all poly, but i'm afraid of just using a more durable synthetic in place of NXT, too....will it help that much? what do you use?
