I also like the efficiency of clipless shoes. I've logged thousands of road/touring miles and many touring/commuting years using clipless. However, I almost always put my clips back on for winter (I went down a couple of times this winter in the snow-clipped in). Sometimes I put the toe clips on when riding the Katy Trail.

The older (and slower!) I get, the more going back to toe clips and straps seems like a good idea for me, too.
