I agree with Dean, from what i saw it'll come down to which one makes the first mistake or gases quickest, I had huge trouble with James hand, and i normally don't have a problem with anyones inside rotation being stronger than my outside. He'll be a handfull at 90 or if he drops down, he could be a BEAST at 85.
One great thing that came out of that session was i know how much stronger my hook has got and it is now going to get much stronger.
