Back when I started cycling, we had quill pedals with toe clips and toe straps. No float. I was just fine with that. That's just the way it was...

Then in the late '80s, I got a set of Dura Ace/LOOK pedals that didn't have float. I was still just fine with that.

My last switch was in the late '90s, to the (short lived) SPD-R Dura Ace, which do have some float. I have not had any problems... It took a little getting used to... but I wouldn't mind trying a zero float pedal again to see if I've gotten to where I like float, or if it just doesn't matter to me.
