I run the Time RXS carbons and I like them. I've never run 0deg float pedals so I don't know how that would feel, but the Time pedal does not allow my foot to move all over the place. I feel as if I have to pyhsically rotate my foot to invoke the float. The feature I really like is that the pedal has a bit of lateral float as well as rotational float. Once again I don't notice the movement in my feet. I was riding Look Keo pedal, with the red cleats, before theses and I found those much more loose feeling then these.
I really like the Time pedals!
