I was in the same mindset as Paramountscapin. 3 years ago I went clipless and only look back occassionally. I started with the Wellgo cheapie SPD's and figured that they would only last 6 months, but that would be long enough to determine if they were for me. I couldn't wear them out and enjoyed their service. 2 months ago I went to the new DA pedals. I liked them so much (wider platform, secure feeling, light, smooth) that I just put the Ultegra version on my old CAAD3.
Every so often, I jump on the 80's Trek 1420 and use the old track toe clips. They are okay, but once again, what kept me?
