honestly, I pay little attention to the commentators. I am more interested in watching the swing, or trying to check out what kind of putter is being rolled so I really can't say on that. As far as instructiors go, I want someone that will tell me what to do, then show me what to do, and then help me to do it. I don't need them to turn around and hit the shot LH (although the guy that I am working with can and does it well), but he can play all the shots RH. And I loike that he is RH because he will stand across from me and let me mirror him for positions which is kind of cool.
