I agree with you there. The method is very simple and while the idea of having different shots for each club in the bag could be a good idea for the more advanced player, for the majority of players who would use this swing it seems unnecessary. If i need to hit it 100yds i'll hit a 56 wedge full rather than a 5 9 iron or whatever, having 10 swings per club over compliactes it for many people imo.
I do like Jim's videos as they are very down to earth and so far and the swing definately has merit especially for the right group of players (i'll count myself in that group). Where you suprised with the amount of power the swing had with it being essentially all arms?
It's not just you. I've read a lot of threads here and unfortunately there's a few people with giant egos that spoil the site. The fish rots from the head down. Fortunately, there are wonderful alternatives!
