What i really wonder: every diver tries to streamline, so why letting an empty alu 80 cft tank float like a candle?
Why not an extra weight at the bottom of the tank to let it float more in horizontal/streamlined position? I think 1 or 1.5 kg would make a nice difference.

It will be very negative upon water entry.
