Just like mentioned in the Sergio thread, and numerous others about tumble. This is the ideal position from which to tumble. Vertical left arm, and clubface just tipping toward the ball. From there... Boom, Pow, Smash! From the camera position you really can't deduce exactly where the clubhead is in relation to his hands. The camera looks to be outside of where his body and hands are located, which would make the club look more inside. Not that any of that would matter anyways. This is where he gets the club to the other side, like Brian talks about in the Underplane video. I really didn't get tumble at all for the longest time. But thanks to reading, and re-reading, and multiple viewings of that Underplane video I think I've got a reasonable understanding. Mostly thanks to posts from Kevin Shields, Lindsey Newman, and lia41985 who we haven't heard much of lately, but who's past posts inspired me to post this. Kevin, in no uncertain terms, told me I had no idea what I was talking about, forcing me to go back and look harder. Mostly I just wanted to be able to understand what I was reading on this forum. There's some VERY interesting stuff around this place.
