I've played ProV1 and ProV1x and shot ok at times with a low score of 83.. I found a NXT Tour S on the course and loved it right away... So I started playing the NXT Tour S shooting a low score of 81 on the same course... Then come along the (New) NXT Tour S and since it has came out I've shot 4 rounds in the 70's 78,77,76 and another 77 yesterday!!!! This ball is awesome it will fly straight, it will draw, it will fade off the tee box but it will not spin out of control like the ProV1's. I can chip this ball, hit high iron shots and have them stop where I hit them and even now have them check back a foot or two. On Drives it seems to really want to run out after it hits the ground adding good positive yardage to the end of your Drive +++++ ProV1 Diffently work great for Some But my ball of Choice is The New NXT Tour S........ Thank You Titleist!!!!!!!
