I have had the opportunity to use a Scubapro first stage with an Apeks second stage and the combo worked perfectly fine in cold waters of New Jersey. Is there any real (technical) reason why we should not mix first and seconds from different brands or models? Or is this a sales driven ideology intended by companies to ensure that anyone buying a Scubapro first stage should not go out and buy a different model of second stage?
