Looking at strong rims, Velocity Cliffhanger, Velocity Aileron, and WTB KOM Tough. I would get 36 hole versions of the Velocities but the WTB only comes in 32 hole. If I go with Cliffhangers (675 grams per rim!) I think it will be plenty strong with any spoke, but if I go with the WTB I think I need to maximize the strength I can get with 32 spokes.

I'm 240 lbs and am hard on wheels, so I want something rugged that I don't have to worry about.
