Frankly, I find it easier to just push my foot down and 'click' instead of having to flip over the pedal and shove my foot in. Twist heal out and 'click' I am free instead of having to yank my foot out at a light and crap it's stuck reach down and loosen the buckle woops. Ok, ride the rat-trap side and the darn cage can catch on stuff. Where is this easier? I don't think about it, just click click. Toe clips are too much work for me.
I second this. I have cages on my communter and clipless on my mtb, and wish I had clipless on both. For the reord, if I can learn to mtn bike in clipless pedals without killing myself, you'll be just fine. Go for it.
