I made my second hole-in-one after a wait of some 18 years.....a nine iron of 132 yards on our signature hole using a ProV1. Six months later, another ace on the same hole, with the same club and another ProV1 !! I just made my third ace (4th overall) on our 17th hole again with a ProV1...! THREE in 18 months, those ProV1s just LOVE the bottom of the hole!
