Coming off a hard tail, it's a tough pick, I'd be happy with almost anything full squish. I like the Specialized, even knowing it's a downgrade from '07. Everyone loves the Rush - well almost everyone. The 6 is what is in my price range. The Rush 5 is VERY nice, and my LBS is saying it's worth the extra $$$ as a longer term investment.
Actually I bought an '06 hold over which was even that much better of a bike. Alot of my buddies ride Rush so I can't knock them. Either bike is more than adequate for XC. Let me know how it works out for you.
