lets see, could we maybe just tighten the belt when we reach the bottom and when we are about to ascend? and since you do buddy dive with your wife you can remind her when she forgets, right? for the 80's at what point do they go positive? just dont take them past that point. last time i checked, lead did not evaporate in air, even when molten. this whole post is really scary.
