My 2 cents......I love clipless - just not in the winter.
It's a whole different ride. I turn to Fred in the winter and keep it simple - Large platform BMX pedals with light hiking boots. (Surley 1X1 single speed)
Plusses - my feet are always warm and comfortable and I don't have to worry about gunk and sticking.
Minuses - My power transference is not optimal, but hey...didn't you say the racing season is over?
