Fred-T's backplate (both short and long) and halcyon's explorer wing both come with four slots to accomodate two tank bands. No STA means a lower COG with the resulting stability.
As far as the QRs, chest straps being " a solution looking for a problem that doesn't exist.", I will respectfully disagree with my esteemed colleague. They work and they work well. They add comfort, fit and flexibility when they are used wisely. As I said, with as many classes that I have DMed for, I have yet to see one fail. Given the option between digging out a set of shears (which I may drop) (or get the tether tangled) and two or three quick pops to get the BCD off of the victim, I prefer the latter.
BUT... when faced with a continuos strap (aka Hogarthian), I will definitely get out the shears and cut away. BTW, has anyone tried to cut this stuff after it has been soaking for a while? Just wondering how easy/difficult the actual cutting process is. I guess it's time to bring some on the next pool session. AND, I will add that task to the rescue diver scenarios.
