These skins are bombproof. My limited experience with mohair suggests it's somewhat delicate, but I don't hesitate to rub skin wax into these with vigor. Rocks, trees, whatever - they don't really seem to get damaged and grip pretty well. Glide improves with break-in, and hot waxing seems to improve it, though I'm not sure if hydrocarbon + fluorocarbon is much better than plain hydrocarbon waxing. BD skins seem to be highly popular with tourers because of their quality, robustness, and availability.
