I've got the molded Ford ones. I too don't really care for the look but the truck kept making a mess of itself. I have not seen any others in person, but did see on a Ford forum someone with duraflaps backed into something and the flap was so strong it split his dually fender in two. I considered switching to them, but found out they are more stiff than rubber, and mine clear most curbs and obstacles. I've decided to leave well enough alone and keep my Ford ones.
