I have an OMM AC Lowrider, now sold by Arkel and a Surly Nice Rack in my closet. I wanted a platform and the Surly was too heavy and realized I never used the lowrider and bought an OMM Sherpa. It's rock solid, light and has a platform. It even extends the fender. I also broke a bolt into the Surly's light mount. This can't happen with the Sherpa since it's just a hole in the platform instead of a threaded hole.
