I think on most every dive operation in south Florida and the Caribbean offers dives in the 80'+ range and you are unlikely going to find anything but alum 80's on board.
Many people with very limited skills do these dives everyday and make it back to the boat alive and healthy.
I switched to steel 100's and 120's a few years ago and I just use them to extend my dive time which is what most people would probably do given bigger tanks.
The solution is simple... leave the bottom with plenty of gas.
Regardless of tank size a blown o-ring at depth (which can be solved by diving DIN) or a first stage failure is highly unlikely.
