Several years back I played the same ProV1 for seven consecutive rounds, 126 holes of golf. It looked like hell the final round and finally decided to put in it in the shag bag, but mostly because the urethane cover started peeling on it - not because it still wasn't up to snuff performance wise.
The worst ball I ever played, endurance wise, was the Callaway HX Tour. Decent performance, but after a round of golf - it was literally impossible to tell what kind of ball it was. I remember one of the first experiences - on the first tee, right out of a new sleeve - Callaway HX Tour. By the 4th hole (no cart path scuffs or anything of the sort - but just typical wear) the logo on the one side was completely shredded off.
They were late to the game as far as endurance properties comparable to Titleist ProV1 standards, but the Callaway premium ball covers are much much better today. I really do like the Chrome Soft, but like I said - just struggle to part with $45 for a box of them.
