I don't think I'll go for an Iro. If I can find one to test ride, I'm willing to consider it, but I am, in general, not an aluminum fan. Plus I don't like the aesthetics of the new big-tube aluminum style. I'd be more likely to buy a Pista and paint it. We'll see what happens once I convert this frame I got, though: looking at specs, the geometry of the Surly Steamroller looks most my style, so if I decide I love building out fixies, maybe I'll start with that for a frame.
