yeah, narrow should have you more forward bite. but wide will be more stable in the bumps. same thing as the sc10 with normal wheels and +3 offset wheels. I really liked the wide hangers on my rb6. I had no desire to tun rb5 parts on mine, plus it was so planted and so smooth that I never felt a need to change it. But then again, i dont rip it out of the corners, I roll in and roll out.
