What a brilliant series of crack climbing videos. I kind of learned some of this stuff decades ago by bumbling around. ("Take!" - or as we used to say back then, "I'm off!") But these guys have thought about it analytically and got it nailed. Big, big difference.
And what a great eight part UK hit list to aim at. If I got up the first four, what a happy little bunny I'd be. (Dream on! Well, why not?)
