My brother has a Stumpjumper and loves it.
I have been looking around and have ridden a few. I tried the Kona Dawg Supreme and found it to be to heavy for me. I felt like I was driving a tank. Then I started looking at the Santa Cruz line because they seemed to be lighter. I think I stopped at the Heckler and the Built. I could not reach a decision on either of those.
I have not ridden Specialized, nor Giant. My road bike is a Look, so perhaps I am spoiled by the weight difference. I guess I want a sturdy bike but not a tank and DS as it necessasry here in the West.
Does anyone have any other suggestions?
