Overall, I think I prefer the current pro v1x to the test ball. I did like the flatter trajectory that I seemed to have with the test ball. However, the feedback I get with the current pro v1 x and pro v1 is superior to the test ball.

Just got mine today, want to go try them so bad but its dark out. Good thing no work tomorrow!

You were kind enough to send me some prototypes and of course I don't know which ones I played (all marked TEST). Great soft Titleist feel, perhaps more distance but I thought I detected greater spin around greens. can't wait to get more!

Played my prototype Prov1x balls today.  Played my best round in about two months.  Shot a 74 but couldn't putt all day (not because of the balls, because of the greens that weren't in the best shape).  Hit the ball more solidly than I ever have…

Since I have switched toTitleist irons,my confidence level in my shotmaking has improved tenfold.I would like to participate in surveys/feedback, and give my insight to help others switch like me.
