Bagger and I were in the Swamp this past week and had a great time.
I came away with some specific items to work on as follows:
1. Pivot. My old "turn" was to turn my shoulders back and load up my right leg with about 90% of my weight. This was causing me to go inside and sway. My new pivot is to start with more weight on my left side and to let the left knee dip a bit. There is still a good bit of weight on my left side at the top - much more than before. I used to think this was a reverse pivot but Yoda convinced me otherwise. This is going to allow me to get the club in a much better position.
2. Extensor action. I learned to add more extensor action than ever before. This will help keep the club on plane and add more structure to my hit.
3. I really learned how to drive down/out/forward until my right elbow passes my "line of sight".
I think these things are going to make a dramatic difference in my action. The teacher can teach but the student must apply.

I'm going to work on the new items a bit and then hopefully I'll be able to post some before/after pictures of my motion.
There is simply no substitute for hands-on TGM instruction, especially if you can get it from the best in the world!
If you get a chance to go to the Swamp or one of the LBG schools - do NOT pass up the opportunity!
