Still working on the same stuff, but I think I'm seeing some improvements. On top of that, I've lost a bit of weight recently (down about 15 lbs so far), which I think has helped things as well.
I played with Barrett today at Westin Mission Hills (Gary Player Course) and hit it pretty well. Ended up shooting 80. With that score, I'm now trending at a 9.7, so it looks as if I'll officially be a single digit as of the next revision. Even if my next few rounds aren't all that great, the next three that fall off my index are in my bottom 10.
