In six years of riding with Speedplay pedals, I have never accidently unclipped and have never had them clog with dirt but I guess it depends on where you ride.
As for as the small cleat. I also use Look in my spin class and I don't feel any difference caused by the cleat size. I do think if you use Speedplay, you want to make sure you have stiff shoes where it might not be as important with Look or SPD-SL pedals.
