I posted on a clipless thread about the KEOs. I also just got the Sprints. I chose them because of the platform, though I had some people telling me to go with Speedplays. I like that it's not too hard to unclip, though I haven't tried doing it in a hurry. But getting the 2nd foot clipped in is a pain--I do fall over, because I slip off when I try to just get going unclipped and don't generate any power. You're doing better than me!

The only trick I can find is to get used to nudging it with your toe--get the front part of the clip in the viscinity of the front of the pedal to help it be right side up more often.

I wish the springs would go looser.

And yes, the cleats are fragile. I broke one already in a fall. But at least it broke and released when I didn't unclip automatically, instead of wrenching my ankle--that ankle has issues already, which is why I'm cycling in the first place!
