I've got three sets of pedals.

Campy track w/titanium spindles

Campy SL road w/titanium spindles

Candy C clipless.

Got the Candy's about a month ago and put them on a mountain bike. I actually like them a lot. They are easy to get out of (its easier to get out of them than get in!) No doubt-I feel more attached to the pedal on the upstroke.

The track pedals are on my road bike and I'll probably leave them.

I've got a cyclocross bike that has the road pedals on it. The Candy's will get a tryout on them real soon.

I STRONGLY resisted clipless up until I got the Candy's-they MIGHT have converted me.

Tried the Speedlights when the first came out-long time ago. It seems like I didn't care for them because they had too much float.
