I think outcomes and simplicity are my top criteria. Porzak golf has given me the best outcomes. Simple, repeatable, great communicator, not too long, easy to follow. Additionally, his outcomes with lower and elite players is exceptional. He has numerous juniors and college players, so his communication is not flux capacitors with centrifugal forces. Its not a new fads or aids for content. He repeats the same principles. Southern Cal for junior golf is tops, where do these players go to - Adam Porzak.
