Fixed-gear vs single-speed for clipless pedals I currently ride a single-speed bike with a flip-flop hub, both for my daily commute and for pleasure/exercise a couple nights a week. I've decided to pick up my first set of clipless pedals and shoes. I've never used toe-clips of any kind or ridden a fixed-gear so I'm curious if I should consider switching to a fixed gear setup.

My commute runs through the city and hits several intersections where I'm stopped by red lights. I know with a fixed-gear I could learn to track stand at intersections, but I'm unsure whether that's easier than clipping-out/in at red lights. Conversely, the same commute involves a large hill that I can't pedal fast enough to keep up with, and I don't know how difficult it would be to control my speed with a fixed-gear.

I'm not sure if there is a non-subjective answer to this, but I'm basically wondering if there is a case for or against fixed-gear instead of single speed with clipless pedals.
Track standing at intersections is more about showing off than about being quick off the stop line. By the time you can track stand consistently (btw, you can learn to do this on a freewheel bike, too), you will have mastered clipless pedals and you'll be able to clip and unclip very quickly. Other than that, riding fixed vs. SS is a matter of taste. Do you like to coast down hills?
