For a period of time, years ago, Aqualung and others produced first stages with one or more 1/2" LP ports and hoses. The idea was that the bigger port and hose would be able to supply more flow with less resistance when used on deep dives and they actually had a measurable improvement over 3/8" ports. But in reality, the increased performance was way beyond what was needed in real world use and the larger ports faded away.The standard lp port is 3/8".
Spare part is the deciding factor.
