In the April 2006 issue of Diver magazine, John Bantin reviewed the custom divers bravo wing and found that, while diving a twinset, if he drained one aluminium tank and left the other full, he created a turning moment. John blamed the wing. Pelagic Exploration responds with a public information service that may be of use. Having said that, Pelagic agrees that divers can dive any way they like as long as they don't endanger anyone else.
Different Strokes for different folks.
