I'm not sure it would help me. Any of the 95 percentile and beyond climbers I've had the chance to talk to simply don't see the world the same way. Their concepts of fear and acceptable risk and how they manage it is a mystery to me.
Though I would agree w/ Scott, I think that Ilgner has done the best job so far in trying to articulate the mental game of climbing and how to work through your own particular obstacles.
