I played a round this past Saturday and one of my friends just recently purchased a new driver. While we were waiting for the group in front of us to hit their shots we were just hanging around talking about new and old drivers. The subject of a driver's life span came up. Can a driver used every week for a few years impact the ball the same as a new driver? A wedge would be done once the groves are smooth and can not grab the ball but is a driver the same? Say after a certain number of hits, the ball will not go as far because it is "used up." No one had an answer but it stuck in my head and I even googled it with no real answer. So I wanted to see what the people of THP think about all this.
