I'm glad to see that you're OK after the fall. Now that it is out of the way, you can worry less and ride more.

I've fallen once in my clipless Sidis. It was in the driveway after a ride and I rolled in the grass. I looked like a beetle bug on its back; my bike was up in the air over me and I still couldn't unclip. All the while utility workers and kids were staring at me.
