Meh. I have both clipless (Look) and toe clips/slotted cleats on my bikes, and honestly I find myself riding my fixed gear bike with toeclips & slotted cleat shoes more often than any other bike. Maybe because the shoes (30+ year old Rivats) are by far the most comfortable bike shoes I've tried, but also because I don't see a really compelling reason to prefer clipless over toeclips/slotted cleats.
