In 2010 the player on the left, Jim Furyk won the Fedex Cup and the player on the right, Matt Kuchar won the PGA Tour money list. Can you tell which arm position at the top is correct or better?
My opinion is that both are correct and neither is better than the other. The swing methodology a player uses means very little in my honest opinion - it's all about what the golf club makes the ball do. Does it work or not? These guys only split $20 million in 2010 so there is nothing wrong with what either of them are doing! Don't get caught up in what the arms or the legs or body are doing unless there is a problem with the ball flight. The swing may be unique, but if it works, keep it.
If either of these players came to me for a lesson I would find footage of when they felt like they played their best and work them back towards that particular swing.
Don't get too caught up in what the text book says you should do - work towards whatever results in better golf shots for you.

The swing that does not work is wrong and the one that consistently works is correct - no matter what it may look like.
