I can't imagine not being clipped in. After years of riding with platform pedals, I got clipless in June. I got my perfunctory fall 2 days later, then a reminder fall into an aloe vera plant when my tire slipped off the curb on a tight turn. I have not fallen since, and put on 1500 miles. I definitely advise giving it a go.

I might note in clipping out, that one is supposed to twist the heel out away from the wheel. Otherwise you might get your heel between your spokes while they are spinning!

Watch out for the cheaper clips and cleats. I have a set that came with the new bike that I haven't gotten my friend's tools to switch over to my originals. These squeak, and only release smoothly in the 6oclock position.
