As all stations said, do the huet, fact is it will save your life if you are ever unfortunate enough to need it. Overwater if I had the chance I would consider popping the door. Don't think I would over land though. A door on a gas strut in auto could open up other problems particularly if there are no split pins in an r22/44 door. The other thing to consider over water is the door damaging the floats on impact. Most other aircraft are a bit more solid in that area but I dont think an r22/44 door would stand in between me and the light to survival in an emergency.
