OP--I ordered some Open Pro rims to Dura Ace hubs a month or so ago from Velomine and love them. They are light and very well built. Wheels were almost perfectly true when I received them and all of the spokes were tensioned evenly.

I went for DA hubs b/c I wanted that bling factor, but if you don't care about that then Formulas are fine and maybe even better for street use (sealed bearing). Either way, I recommend the Open Pro rim as well as BUTTED spokes. Light spokes make a big difference.
