Greg G, I'm really enjoying working my way through this thread. Very instructional. You're clearly a serious student of the game willing to do the work necessary to improve.
I really like the trajectory of your forehand shots from the back view. Very nice. Mine, on the other hand, are all over the frickin' place. Hopefully I will learn something from this thread.
Interesting also reading about you having to deal with the various injuries ... which I've had my share of also.
Looking real good. Best wishes for continued improvement.
