Randy, the point of balancing the rig for the dive is lost on this discussion. With aluminum and a wetuit, the weight should be removeable, as in a weightbelt, so that one can get up in a bad situation. The point of "simplicity" lies in not complictating the rig with multiple bc's, and therefor adding more problems while trying to solve a self-inflicted problem (using the wrong tanks). We ( WKPP) do NOT use integrated weight nor do we use steel backplates with almuminum when diving wet in the ocean. If we are using a drysuit and aluminum, then the integrated v weight and the steel plate can ofset the suit, but then the problem is that if you take the tanks off in the water to clip off to a tag line in rough weather, they are at risk of being lost. I would rather lose a weightbelt. Steel should only be used with a drysuit, but then steel on a boat is a problem walking around in rough weather and for the reason mentioned above, and is totally unnecessary . The extra gas in 104's for instance, is only equal to one more aluminum 80. Take a stage bottle if more gas is needed, but then what kind of moron is going to incur that kind of decompression liability in the open ocean? I can see taking a stage and doing the whole dive on the stage , preserving the backgas for emergency and or for more dives, but if not to offset hoovery or excessive exposure - neither is too smart. Aluminum doubles are negative 6 full of air, roughly half of that with 50% helium, positive 6 empty. The weightbelt used depends on the person's overall buoyancy and on whether or not that person is using a droppable canister light ( itself usually 6 pounds negative in salt water). The total rig should be balanced for the full range of gas use, and should solve all of its problems wiht a flick or the wrist, so to speak. Only the worst irrepsonsible idiot would allow diving with a wetsuit and steel in the ocean, and I can attest to the body searches for those who have . This is right up there with the bottle marking stupidity that we see out there being taught and instituionalized. Same idiots, different stupidity. I hope you are reading our web page wrong, if not, I will correct it. My bet is you are following some link. I can not be responsible for the pesonal preference or other insanity that springs up on other people's web sites.
