I never liked the amount of float on my spd's - didn't really feel like they have much. That was like 15 years ago, though.

My Time ROC Carbon Atac's have plenty of float for me at the moment, and like the Crank Brothers I could switch which cleat was on which foot and get 17 degrees of float rather than 13 degrees (which I have now). Just fyi if you're looking for float.
