In reply to Chris D: I posted praise for Dave a while ago just after he did AD and got a right good slagging from almost everyone (quelle surprise!).
The general feeling among North American sport climbers seems to be that Chris is God and Dave is brilliant, but a long way from Chris in terms of overall ability. People see him as a boulderer or very short route climber, able to crimp like nobody - just watch him send the Mandala and you'll see what I mean about crimps! AD is also relatively short, but, like I said in my last post about him, you absolutely have to acknowledge him as incredible for doing AD like he did. If it took Wolfgang that long, then it is obviously a very, very significant achievement to have done it so quickly.
He's absolutely tiny, as well. Pretty short and stick thin. Some say this is how he manages stuff, but just wait until he does the same kind of bulking up that Sharma did and develops some real power. I can imagine people like Dave and Sharma doing 9c in ten years' time as long as they don't burn out and maintain their infectious enthusiasm for everything (and Chris lays off the herb a bit).
And, in my opinion, Dave would absolutely piss all over Hubble, as it is very short and pretty crimpy.
