How different do they feel? I bought my first mountain bike in October, a 2011 575, and really enjoy the frame. Seems the rockier and ruttier it gets, the smoother it feels.

I keep reading the the 575 is plush while the SB66 will have you feel more of the trail. Does this mean the SB-66 is tougher to control?

How does the SB66 handle and corner different than the 575?

I'm on the fence about ordering a SB-66c from JensenUSA but not sure if the SB-66 will set me back due to being too high performance. I really enjoy rocky rutty single tracks, bermed switchbacks and speed. I hate climbing but it's the only way to get to the good trails so I'd like a good climber.
