I want to get a dedicated backup lift device in case of bc failure. I have recently taken DP/AN classes, have tried only dsmb's as part of my training and practice afterwords. And I can see the advantage to carrying some kind of device that is a bit more robust/has more lifta (not just a skinny dsmb I've been using). I do not plan on lifting junk off the bottom. But I'm struggling to understand the advantage of one type of design vs the other. For instance, I've read that, when shot to the surface the open bottom type are easier to fill but they flop over then the gas spills out, but with a bottom baffled unit it's difficult to deflate when at surface when one wants it to be quick about it, there is nothing quick about that type. What do divers prefer and why?
