So far, its a bit of a headache, but hey it was a free ride with $0 invested (I even had the bar laying around). The hubs are Velocity track hubs, but they currently only have black in stock. The silver are "on the water" and should be here first of the year. I went through them because a) they are 4 miles from my house, and b) our shop has a great relationship with them so I actually get a bit off wholesale on them... worst comes to worst though I may just pony up for some Formulas from another distributor.
