I shoot in the mid 80's usually, and although I've never had it measured, my swing speed is in the neighborhood of 110. I have been using only yellow DT solo's for the past few years because I like a yellow ball and they say Titleist on them. Last weekend I got matched up with some low handicap golfers, and they were questioning my choice of ball. Like I said earlier, I don't really have a reason for choosing that ball except that I prefer yellow ones. What exactly would a firmer ball do? Would it increase my control and allow me to hit more GIR's? I think my distance is fine, and I putt well with my DT's. Would changing to a firmer ball really change my game?
I haven't played with a different ball since I broke 100.
