The person in the video is John Erickson, aka 'Lagpressure' on some other message boards. He used to be under the tutelage of Ben Doyle. Former Australian and Canadian Tour player as well as a former All-American in college. He says he drive loads with the right arm so I wouldn't label him a 'swinger.' 4-barrel...I have no idea how exactly you would tell that. But it is a superb motion. I would love to see him become a member of this forum so he can give his thoughts and experiences on TGM.
