I just moved away from Time (hard to clip in, float was sticky) to Looks. Although I really wanted to spend for the flashiest & lightest, I found that these tend to be aimed at men & therefore require more force to get out of. I guess men are scared of pulling out by mistake - women are more concerned about being able to get out easily. So I ended up going w/ the bottom of the range - the Look Easy as this has the lowest force of all of them to click in & out. Much better than the Times in terms of clicking in & also having free float (I use the red cleats, rather than the less floaty greys that the pedals come with).

We do a lot of bike fittings for customers & have found that the float of SPD-SLs is 'stickier' than Looks - Speedplay are the free-est of all (some people say it's like standing on an ice cube). I didn't go w/ Speedplay because I didn't want to always wear covers on the cleats (they will really mark wooden floors inside & must not get grit/mud in outside).
