I got to play with an M2 today. It has the Graphite Design Tour GP AD 6 shaft in stiff flex, set at 10.5 degrees. It was impressive. I was hitting some good straight bombs on a tough course. I fight a pull/hook, so even when I pulled it a couple of times it wasn't completely horrible, definitely forgiving. The sound is also kinda interesting, easy to get used to though. It was crazy, the easier I swung this thing the more the ball took off. I can reliably say I was hitting this thing in 285-305 yard range. Which for me is probably 25-45 yards farther than any distance I've ever hit. Let's see what happens when I take it a second time. My buddy that lent it to me may have a difficult time getting it back.
