When I got back into biking a few years ago I started back on platforms. I then went to toe clips and now use SPD-SL's on all of my bikes. When I bought my 3rd road bike a used Trek 1200 I put on some toe clip pedals that I had in place of the platforms it came with. I rode the Trek for about 2 days and immediately ordered clipless pedals for it. I could feel how ineffeicient the toe clips were compared to clipless.
