oversea:Dive Rite advertises it as a singles wing that may handle small doubles. the taco is not a huge problem, just something I noticed
Right, and I was expaining to you the reason for the problem. That wing is at least the width of a single AL 80 too wide (probably a little more) for a single tank and this causes the wing to wrap around the tank too high because the inflated part pulls the non-inflatable part that would otherwise be trapped under a set of double tanks directly up the side of a single tank.
