I am looking into buying a mtn. bike this week. I have a Trek 4500 on order and the shop for a comparison ride is going to build up a Specialized Rockhopper. Then I get to choose between the two.

I see Sundial owns a Rockhopper, does anyone else ride either of these as well? Can anyone tell me pros and cons? I know that in the end it is going to be my chose and how I feel in the ride, but I'd still like to hear thoughts.
