Thanks for your helpful responses thus far.

In viewing Looks website for pedals I'm a bit confused. I read the info on the different types of Keos. I'm wondering are some of them easier to get in and out of then ohters? I saw the tech stats for the degree of tension adjustment. I assume the lower number means least amount of tension, and thus engagement/release?

That is good info about the SpeedPlays loosening up with use and lubrication. Gives me some more to think about.
