Tried using the search function, but nothing yielded the answers I'm looking for, nor did google/wikipedia.

From what I understand, cleat float is the ease or difficulty of clipping out of the pedals? Different degrees of float give different feels in and out of the pedal? Correct me if I'm wrong, which I'm sure I am.

I'm looking at getting a pair of Look Keo classics, shimano shoes, and obviously look cleats. But, which float/color would be best for a beginner? I'd like to be able to clip in and out easily and promptly.
