I've got the form in front of me! Squee!
I was in street shoes, and as C observed that's mostly how I'll be riding this. If I do plan on a big trains'n'Brommies tour, or something, I can fit my Times from another machine.
My hardon for simplicity is pointing toward the 2-speed. One for rolling, one for hills, and the efficiency and weight savings both make me quite keen on that. Standard gears look fine.
