LOW TECH, HIGH YIELD
I don't use launch monitors. I'll get on one, but generally I can tell by the flight. If the flight's right, then it's in the ballpark. I don't need the computer to tell me it's right.
If you play baseball or basketball, you just have one look at the target and you go. In golf, we tend to stand over the ball too long and look three, four, five times, and then let it go. So with my putting I try to take one look and then react to what I see. I'm just trying to be a little more athletic about it.
