I am a senior golfer at Smithfields CC here in Easley SC. I used to play different golf balls each round, just whatever I picked up, no rhyme or reason, Titleist and something else, then something else, then Titleist, and on and on. And I played pretty well. I finally settled down and started playing Pro V1x (and every now and then Pro V 1) and my handicap index has dropped from around 7.8 to 5.1. Today I shot a 71 with the best ball made, ProV1x. Thank you Titleist!!
