HED's quality has always been outstanding. They charge premium prices, although Vanquish rims are relatively sane in comparison to some others. HED stuck to their guns on not liking carbon brake tracks, and that's noble as hell. Carbon was never that good a solution for rim brake clinchers - it worked under certain conditions but you can't restrain a mass market product to just those conditions. Also as you work toward solving one problem (heat), you create another (brittleness). Vanquish rims are disc only, so the only thing they "solved" was removing the parameter of heat resistance. The dynamics of carbon clinchers for disc brakes allow you to avoid brittleness thanks to no need for heat resistance. When you see a disc brake wheel/rim advertised as being built with heat resistant resins, that's a bad thing. You want resilient rims, heat resistance is more or less mutually exclusive with that. If you are looking for disc brake wheels/rims from a front line name brand and don't mind paying that premium, Vanquish are a good choice.
