My commuter is my beater, so I need the triple. While I could do it, I don't think I will as it will limit what I could do with it.

Especially so since it is geared perfectly for towing my trailer and kid. That adds about 50-60 pounds, which makes the bike too heavy to get going on the middle chainring. Otherwise, I save the granny gear for climbing the bumps I live near (really steep bumps).
