I received a sleeve of proV1 balls before xmas. I have had 2 astonishing rounds with them. First round 71 (par 70) with 25 puts and 70 (70) with 23 puts. I have always used Titleist balls but these helped my short game so much. I have recently retired and playing more golf but the balls helped my putting and chipping no end. The big test will be playing with them in the summer.
