I am probably one of the last holdouts for clipless pedals. As I was told, once you try them you will never look back. That has been the case for me.
I must say I don't miss the rat trap pedal backlash when my foot slips off a pedal and the teeth are driven into my shinbone.
The question about the use of velcro. I also don't miss a shoelace coming loose and winding around a pedal spindle. This is especially fun with a fixie.
