In reply to ADHDean: Well, 'dieting down' I assume refers to losing body fat, not muscle, right? After all, you don't diet to lose muscle; you diet to lose fat and to muscle you reduce the intensity of your resistance training enough that you lose muscle mass.
The ideal build for climbing is low body-fat and medium muscle mass in the right places (mostly, but not exclusively, back muscles) with high recruitment.
Basically, power to weight ratio.
And, having said all that, you only need to look at John Dunne to see that you don't have to have the textbook climber's build to climb E10.
Just get on with it and go with what you've got, mate. That's all anyone else does. Refine your physique if you want.
