Dang Andy, no wonder you are a scratch golfer.

I hit something like 330 according to GPS. It was a par 4, something like 340 yards, actually putted up on the green for a birdie. As the summer wore on though, I started to lose a lot of distance with my Hi-bore. Anyone else have the same problem? I'm probably hitting it maybe 275-285 whereas earlier, I was consistently 300-315 with it.
