No. Do not. Fox 40's are more lively, lighter, and more apt to win you races. Avy's are more sluggish, but they are plush. I would stick with a fox 40. I have ridden both, and own a fox 40.
This reply is a prime example why one should not use drugs.
I have an avalanche 1.0 and while it is a nice ride, I would stick with the Scott. I will be replacing my Avalanche this week with a Wolfridge 6.7 or 6.8. I like the avalanche frame and will probably use it in the future for a build.
