Just picked up a Prince O3 Tour (the original version mp) to give it another chance. Had one when they first came out, gave up on it, regretted selling it. What strings and tensions have people found that work or would recommend? I'm starting playing again after a layoff (3 years now, 14 years before that). My game was serve and volley but it's transitioning (I think) to a more baseline/all court game. I'm moving my grips from eastern to semiwestern on the FH side and might be going back to the 2HBH. Haven't had any arm problems but I'm old and brittle so as much as I'm curious about poly hybrids I'm not sure if they're the best idea. Thanks. BTW, currently using X-1 biphase in my Slaz X1's and like it - crisp but not hard and pretty good tension maintenance.
