For years I used to play whatever ball I can get my hands on, including old balls I fish out of the water. Last year a friend gifted me a box of Pro V1s, and I swear I can visualize and shoot better with them. I feel like they give me both distance on hard shots and touch on finesse shots. I've tried V1xs, too, but don't like them as much compared to the V1, seem more mushy. It's probably all in my head, but in any case I've been playing only V1s for the last 6 months. I'm sure my bank account has taken a hit, but the plus side is that I'm much more deliberate now and don't hit stupid "hit and pray" shots any more. I don't lose as many balls as I used to, and actually had to retire a few balls due to shell damage, which had never happened before the switch.
I played the TP5 and TP5x, didn't quite like either. Last week I bought a box of Z-Stars and TourBs each to see if any of them can replace the V1s.
