I want to know when something feels good or terrible so I can understand why. Everything thing else falls in the 'I can make it work' category. And I'm interesting in at least trying anything that supposedly reduces spin so I can see if its BS or not, and theorize why it does/doesn't work. I mean, I've been gaming 13 year old irons this year that don't suit me at all, just because they're there and I can make them work. I'm only now switching to some that fit me better. I don't use manufacturer head covers, so if you want to know what I'm teeing you have to ask. I like to know about it and try things, but in the end I'd rather work on my game.
