All, I use Dunlop AG300's, 58 lbs with OGSM 17G and X1 17G, 2 racquets have a full bed of OGSM, 1 has a full bed of X1. My 4th racquet is in need of strings. I'm an all court player, groundstrokes are my strengths, hit flat, OHB, can hit thru as well as slice. More of a placement guy then power guy but can hit with power when I need/want to. I have a pack of SPPP, 17G and want to try it as a hybrid. I have a pack of X1 17G, OGSM 17G or Tech Multifeel 17G. I string myself but haven't done much poly so the tension for poly's is a guess for me. Anyone played with one of these combo's and liked it or hated it? Any combo you would try over the other and why? Based upon my current tension, tension suggestions?
