I switched my 66 for this and it was good choice. Dualcrown feels much firmer and bike is more stable through rough stuff. Still it doesn't feel too plush like DH rigs and it jumps well.
I'm thinking of doing this sort of thing (Supreme FR + Dual Crown) and using it for occasional techy downhill but mostly jumpy/flowy park. Dedicated DH bikes don't jump well enough for me. Thanks for the reply mate!
