I'll stick with my crank bros. No noise. I'll have to wait a bit though as I was dumb enough to ride in on Jan 5th and try to cross an ice covered path.
I did not unclip in time before hitting the ice.
What I did do is twist just enough as when the exposed heel hit the ground and take the weight of the bike and me, the clips were still engaged.
I heard a crack and hoped it was just the ice. Nope, it was the fibula in two places.
It will be interesting getting back into clips in March (or April).

At least I solved the daily question of "is the weather nice enough to ride in or shall I take the car ?"
