I rode sans clips for some months, and then switched to clipped. I found that I can get a smoother pedaling stroke going, use my hamstrings to support my power strokes, and the "issue" of getting out of the clip has never been a problem. In fact, just the opposite has been my problem: they come out (and yes, I’ve tightened them). I have a pair of the Shimano-324, and use them on my singlespeed. This gives me the option of powering or cruising. The downside: they’re heavy.
