I loaned out my lp85s (filled to 3200) and lp95s (also filled to 3200) today. So I dove my wife's al80s, 2 al80 bottom stages, and an al40 O2 bottle which I had on a leash. That's alot of junk in the trunk and its way overcomplicating to the point of dangerous if you're just beginning technical or cave diving.
But, if you're just beginning technical or cave diving why would they dive 2 bottom stages and an AL40 of O2? Instead of just sticking to backgas and maybe one deco gas? I understand your point, and I dont disagree with your recommendations, but it just seems kind of an apple to orange comparison.
