I've had 3 prereleases on my shifts. All on powdays. 2 have been one ski releasing to the side on compressions and I've skied away. Another one was popping around in pow on the side of a green where I double ejected out the front to lawndart faceplant waist deep upside down... The lady troller behind me was bent over laughing having a hard time getting out the words "are you all good?".
As far as I can tell they are set up correctly. I've checked at home after each instance. It's a real bummer to have to ski on eggshells with them.
