I realize this is a few months old, but in my search I came across Mudhuggers. The US distributer is shop.cyclepathpdx.com/mudhugger-usa/ (I'm new so I can't post links)
I like the design but it was going to take a bit more work to get them to fit my Surly Troll. They were moderately helpful as far as service goes, but I wasn't willing to try a heat gun to get the most custom fit.
