Wow, what a trip. I just spent a good amount of time re-reading this entire thread.
The good - My index is down from a 16.4 to an 8.5. My putting has improved. I am on my 2nd driver, 2nd 3 wood, and 3rd set of irons (and 3rd putter). Not too bad since the end of 2006.
The Bad - I have noticed I am still bitching about the same **** I was bitching about nearly 4 years ago. I really need to work on distance control. We seemed to have lost some golfers.
