6bee, I'll repeat I never made those statements. I said I know Hogan's swing and can demonstrate the model very well.
I did not say I know more than HK. Please stop attributing to me what you think I said. I said so far I haven't learned anything new from what I've read about TGM. I've also said, since I purposedly avoided reading TGM, I don't really know it that well - so maybe there will be something new for me there.
Keep in mind, I also have spent a quarter of a century reseaching the golf swing, and perhaps hit a lot more balls than HK ever did. At some point you will be free to compare my swing(s) to his or anyone elses' for that matter.
You've seen his swing sequence on Lynn's site, right? Need we pursue this? You are painting me in the corner of being his antagonist, and I'm really not. As I stated above, I truly believe HK and I would have gotten along extremely well.
I've tried to contribute here to a degree. Yes, I do tend to be a bit tight lipped. Recently, I gave my specific thoughts about Hogan's right knee. In the current topic, I'm pointing out my thoughts regarding the left arm.
To answer your most recent question, where the left arm goes on the take-away depends entirely on the swing model. In a few swing models, it stays tight to the chest during the takeaway. In many, it is not in a tight association. In others, such as Trevino's it moves away.
However, the topic was the left arm on the downswing, not the take-away. Correct?
I previously said it should not, on a full swing, be in close contact with the chest during the downswing. It's an erroneous concept and could certainly lead one astray if taken literally.
It's much easier for all concerned, to write clearly and accurately, not so understanding is difficult, but rather so misunderstanding is.
