I switched to commuting SS from one of my road bikes. I prefer not having to mess with deraileurs and found that I really only used 2 gears anyhow. My commute varies between 16 and 24 miles round trip on flat road. I just picked a gearing that lets me spin at a comfortable cadence at ~20mph. Starting from a stop is more work than with a geared bike, but I spend far more time at cruising speed than I do leaving stop signs/lights.
