I'm a devout Catholic. I have a phobia regarding the number 6. When I opened a new sleeve of ProV1's that I received as a gift, they all had the number 6 on them. -666- I went into the Pro Shop and asked the Pro Shop Attendant if I could exchange the sleeve of balls for a different number. He gave me a sleeve with the number 4 on them. That's the ball I used when I got my Hole-in-One. Thank you Jesus !!
