Good commute today, first proper ride with my new Rob Roy build - it's not completed yet, and still lacks brakes (riding it fixed right now). I put it together last night and could barely stay off it, so I figured I'd ride it a bit today and see how she feels. The steerer tube still needs to be cut down, too - all will be done very soon though.
Riding brakeless was a little hairy - at least in the mental sense, in actuality it wasn't a big deal apart from a crosswalk hesitation from a couple of pedestrians, they ended up NOT walking after I hammered on a desperate skid stop - I've learned to mostly read ahead now anyway just from riding a lot (fixed or geared) so the timing/preparation is near second nature most of the time.
The bike rides like a dream, and I love it oh so very much, I'll post a pre-complete pic!
