[Matt]

I read an article a few days ago where he said something along the lines of, "When my left arm is on the same angle as my shoulders at the top, I can't get 'stuck'."

I honestly don't see how that could have anything to do with anything. That, combined with all the importance the shaft plane is getting, makes me wonder what in the world he's being taught. Obviously he's a good enough athlete and has great coordination, as he makes it work somehow. He's probably just not doing what he thinks he's doing.
