This is going ot be a stupid question, but since I don't know the answer I'm going to ask. Would a failure of this type at depth increase the chances of your first stage 'freezing up'? I've never seen this happen, but I have seen compressed CO2 tanks blow out valves, and the frost forms rather quickly. Not sure if the same would happen with nitrox/trimix/quadmix/etc. Thanks!
