I have a dozen in my bag and I have some random dozens waiting for me. I received a dozen as a gift (Titleist DT Solo) and I won a dozen Callaway Hex Black Tours from a web site. I seem to like Callaway balls the most so far and have a few different boxes of them.
If you are thinking this way, you should probably quit. I play to relax. Whether I play good or bad I always have a good time. Sure, playing better is always great, but golfing for the regular guy is more about havign fun.
With my group of friends, it's gotten more popular with us. I'm 32, and ten years ago only one of us regularly golfed. Now five of my buddies from back then do. We usually try to go to the cheaper places to play due to the economy, but we still go.
So far I've been a Callaway guy. I was out testing clubs last year when I decided to buy a decent set of irons, and Callaways just felt great. That led to me trying Callaway balls which I also liked alot. I will play other balls though.
