Don,that's kinda what I meant in that with being insulated by dead air spaces the conduction would still conduce away more energy than the relative convection advantage argon would have.And I was assuming that argon and indeed He based back gasses will be drier than air and hence absorb more moisture enhancing evaporation.Be aware cold water diving is all theory to me as I live in Florida.I dive mix on occasion and it does feel much cooler in my mouth,throat and chest.
