Would appreciate some string help. Approaching 50 yo, NTRP 4.0. Only played with a demo for about 30 min, and bought this racquet on the recommendation of a pro. Had it strung mid tension with Lux Fluoro 17 (also recommended). Have now played with this racquet about 2 hours, and just not "feeling it." When I played the demo, it really felt great. I can't remember the string. In the past, I've only played with multifilament( most recently TF X One BiPhase 17, which I really like). I play an all around game, not extreme top spinner, one hand BH, and not a string breaker. Do you think I should just restring with a multi. I know that this is a real "players racquet," and I usually generate a fair amount of power. But the current setup just feels dead. Not getting any pop. Is it the string, or should I be looking at a different racquet. Maybe I'm not up for this racquet. Thanks in advance for your help and suggestions.
