I haven't played for a couple of weeks. I had these prototype balls sitting in my room. I nearly almost forgot them when I ran out the door. Lucky I remember! 17th hole, 210yards, downhill, strong right to left wind, 5 iron, perfect shot, at Conway Farms GC. Second hole-in-one of my career! Awesome! Just too bad there wasn't a BMW on the line. :) My new lucky golfs!
