I've ridden a lot of 42/16 on the road and it's a good gear. What I do now is ride a 15/17t fix/fix cog and swap the wheel orientation depending on if I wanted to go fast or commute, run errands, noodle around or otherwise not go too hard.

"Now" is relative of course, as I haven't owned a fg for road use in a good 15+ months now. Working on it...

also live jazz is good.
