I see this up here all the time. We have people come up here and dive a wreck called the Vienna (130'-150', temp - 40F at the wreck) in Superior. People think they can strap on a 80 and a 30cf pony and be all right. Sure, until something goes wrong down there. People get in trouble easily on that wreck. Thirty cubes isn't much at 100' and even less in an emergency.
An 80 and a 30cf on a 130'-150' wreck? *cough* Sounds like Darwinism in effect rather than an indictment against the 30cf pony.
Also, while 30cf "isn't much at 100'", it's better than nothing - no matter how you sling it.
