I am new to public safety diving. I am a member of a volunteer group in Connecticut. One of our officers uses only 63 cubic feet tanks. He explained that he does so because he has a short torso and it is more comfortable when sitting on the edge of our boat waiting to dive. He said the team limits diver bottom time to 20 minutes for safety reasons and to preserve attention span. It seems that the smaller tank makes sense. I rarely use up an entire 80 cubic feet tank when diving, even on long or repetitive dives. Although I'm taller than he is, the shorter tanks would seem to be more comfortable out of the water for me as well. Is there a reason to use the larger as opposed to the smaller tank? Thanks in advance.

PS I dive with a 30 cubic feet pony bottle. I don't know if that information affects anyone's opinion.
