If you actually need to remove a tank in a constriction, I find weighting the least of my worries as I'm touching the rock?

It isn't nearly the problem getting through restrictions, as it is trying to donate a tank. However if your only source of weight is your tanks, then you will have to drag yourself along the ceiling to get through a restriction. It is much better to have just enough weight on your harness to counter the buoyancy of a deflated dry suit.Originally Posted by OutOfTest

That only works if the restriction is down low and able hold yourself down. Many times by the time you enter a restriction body position may no be conducive to allow venting of drysuit or wing. IMO, dealing with buoyancy shifts from tank removal in a restriction only complicates the problem, or inother words it just gives Murphy more opportunities. Just a word of warning to people who depend on tanks for negative buoyancy and enter restrictions with possible tank removal. I think you and I know of an incident where there was a fatality this type of situation.

One thing that I see that we should have all been taught in ow class is to weight yourself so you can do a 10' - 20' stop with nearly empty tanks. I see people all the time in Faber tanks and drysuits with no weight on their harness. This works as long as they are coming out with plenty of gas but if they ever have a real issue they are going to be stuck to the ceiling. I have seen instructors teach this and I really don't understand why.
I learned this the hard way the 2nd time I dived Faber 120s. Did a recalculation on 3rds for a short dive with an intro guy in JB on 1/6s. I put 6lbs on my harness after that dive. Another problem is stages when they get low and causing positive buoyancy. All apart of a learning process! This weekend begins the learning part of the DPV process.

People, please stop telling backmount divers to isolate at the first sign of a problem. Isolating a set of doubles is pretty much never needed. Ever. It just wastes time.
Shut down the offending post instead.

What are doubles?
