In reply to badgerjockey:
Well, naturally it depends on where and what ya climb. But generally you only need one or two "alpine draws" per route, more often than not you don't need a single one. That was certainly true on the odd grit routes I've climbed, and pretty much everywhere else (spain, italy, france, swithzerland and scandinavia).
Where you really need 'em is easy alpine terrain. Where I and most others seems to use them mostly. On alpine routes (and winter mixed climbing) I generally carry more alpine draws (between 4 and 6).
So, in short, you can... but more often than not, it is not needed and fiddling around factor is often too much, especially the extending (unless you have them over the shoulder, when they get tangled up).
