I'd used Shimano SPD-SL for quite a while and they worked well, but a while ago, I got the 'upgrade bug' and bought a set of Look Keo 2 Max. Immediately upon installation, I felt they weren't as easy to get in and out of as the old Shimanos. I figured it's just take a bit of time for them to break in. Sorry to say, I had a 'can't get out quickly enough' fall before that happened. On the recommendation of some riding friends, I tried a set of Time Iclic 2 pedals/cleats, and I'm very happy. Hands down, the easiest in and easiest out set up I've ever experienced and also very secure once clipped in. YMMV
