Randy, again, adding v weights to aluminum tanks with a wetsuit is just as dangerous as using steels to start with - you can't get rid of the weight. The wetsuit compresses as you go down, and the bouyancy changes. The idea is to use the belt ot offset the buoyancy swing of the tanks , maintaining a balanced rig within that swimg range for which no convoluted solutions are then necessary. I realize this breaks the hearts of the bondage crowd, but when you see somebody wearing bondage wings or double wings, they either got screwed by some dive shop savant, got hoodwinked by some half wit "instructor" or they themsleves are mongoloid stupid. Aluminum 80's are CONSIDERABLY lighter than 104's. Adding weight to aluminum 80's for dryusuit diving DOES NOT make them as heavy as 104's. The buoyancy EQUAVALENT is achieved by virtue of the fact that the freaking tanks are much smaller. The idea of using them in that fashion would be to have a lighter rig walking around on a boat - much safer, much more practical. Big tanks imply bail out gas for traveling, as in a cave. I hate responding to aguments like this where the basics are so poorly understood, but you claimed you got this slop off of the WKPP web site, which is not true, and the fact is that the dangerous nonsense being recommended sounds like IANTD 101. You are not picking up the logic of what I am saying ,and that is extremely frustrating. The explanation for that lies in the fact that what is beeing taught out there is so extremely piss poor and is done my such retrograde morons that there is little wonder that nobody has a freaking clue. The only good benefit of that is the fact that we have nothing but wide open cave to explore no matter where we go, thanks to the widespread practice of clueless oblivion that prevails in diving.
