Although I took my survey last week, I have since played 4 additional rounds with them, and then switched back to my prov1 and learned more and wish I was taking the survey now, I have more good information to pass along. The prov1 flies higher off my driver than the test ball and does not carry as far. Also recognized my irons and hybrids were carrying shorter with the prov1. The test ball feels more like provix off all clubs and checks up really well same as prov1x. At this time I would buy a dozen test balls if I could. I hope they come on the market. If I knew how, I would contact Titleist and ask for more balls. I have only one left and it has cart path rash and is in very used condition. However, I got a total 7 rounds out of my gift test 3-pack. Whiskey
