I bet I have five plus dozen in my bag. I hardly ever lose a ball,but I like to try different balls and I will stick a couple of balls in the bag and some of the guys will give me a ball to try and it gets dropped in the bag for a practice round and they keep growing in the bag. I play almost everyday so the bag is always in the truck,so every couple of months I clean out the ball pocket and take 2-3 dozen out. So after I clean out my bag I usually start with about a dozen or less new balls. and the cycle stars over again.
