Just wondering if you compared those products to Pyramid's fender extender and rear fender hugger? I've tried to find a decent picture of their rear fender hugger and can't, really like the one you have but would like to have your opinion.
Styling is a personal consideration, but the deciding factor for me was the increased tire clearance of the Skidmarx vs. the others. For a bike that may venture off of paved surfaces, the thought of packing it with mud or sending a piece of gravel over the top with a DOT knobby made the others look suspect to me.
