If I can find a deal, I'll try to get an Alfine 8 IGH for this frame, and use a bar end shifter for it. Otherwise, I will build it as a singlespeed. Where I live now, it's not all that hilly so I could safely run a fairly tall gear and get around fine. One short hill on the way home would give me a little trouble until I managed to HTFU, but otherwise SS would keep the bike relatively light (as light as a commuter with fenders and a rack can be).
