I'm long and have a small waist so most 3/4 shorts look like board shorts on me! Thinking of getting some Singletrack 3/4s. The spec says they have a pre-curved knee which probably wont line up with my knee as I only need a M. How curved is the knee? My LBS had a set of XXL and I don't remember much of a (any) curve and I can't tell from the pic in this month magazine. Cheers
