His personal goal is predictable results through end ranges of motion.
He has made a career of treating the swing as a science.
I take his advice knowing that he won many tournaments with his previous more traditional swing. He is a very gifted athlete. He did not start from scratch.
I am a big fan of his triangle setup. Especially, his description of the upper and lower arms. I also like his notion that the butt of the club stays in front of the chest. This is great stuff.
