I like Trahan's swing except possibly for the longer clubs. I don't see the toe line business working with a driver. I think that is why Trahan recommends shorter drivers. If you use an SA setup this is even more difficult as having the arms hanging down with and angle or preset wrist cock makes it easier to swing up high like that. As others have commented it makes sense to do all of it to get it right which means no more single axis.
Trahan's science claims also bother me a bit. His science rational for a shorter turn producing more distance then a full turn is rather flawed. Also a while back he had a physics expert on his web site who had a fake online degree. Not a real confidence booster.
Anyway Stan, I thought that your doctor told you that you had to use a swing with zero turn? It sounds like the limited turn is okay?
