I understand that EDGE makes a nice product, but have never ridden their wheels. I've been on Zipp 303 Tubies for two years and have no complaints at 185lbs and 4000miles.
I also have a set of 404's clinchers in the basement that came with my Archon. I only ever rode them twice and decided that I liked the 303 tubie better for my road bike and threw them on my TT/Tri rig. They're for sale if you want them. I've got a set of 909's for the Tri bike on the way and won't use the 404's hardly ever.
