Dr. Bill,
I like your weight formula. It fit me pretty well for my freshwater diving.
Concerning the snorkel, when we were doing parascuba jumping in the USAF, many of us would put the snorkel under our knife straps on our leg, usually on the inside of the leg. That way, we had it if we needed the snorkel, but it was not an entanglement hazard during our jump.
Parascuba jump, Buckner Bay, Okinawa, 1968.
