I think I've reached my limit with Crank Bros. Yesterday I had a really tough time clipping in and I think i want to try SPDs.

The built in "float" as the cleats wear away like butter, the problem clicking in, etc. Might be my personal experience but I think I'll go SPD. I know gastro and Pete uses SPD so that's enough endorsement for me. I think I'll try to get one of those platform ones. I'll have to dig through the archives to find some references.
