Hmmm I'm sensing you don't particularly like Rock Shox? ha ha. Ya if you got the cash and don't mind tinkering with the 5th element for for it! I can't say anything about the avalanche, since I've never had any experience with it...but from what I've read and the fact that you see em poping up on bikes more and more, I'd have to say it's worth a shot. And since you're into 15' drops, those two might take that abuse more than the fox.
