The easy rule is that you give whatever you are breathing.. If this is a stage, you give the stage. So, the need for a breakaway is theoritical. However, I do believe that in certain instances, (reg. switch for example), the theory may not work. In this case, I am not looking for something to hopefully slide. I just want to give it (or take it) right away. The attachment for the primary regulator to the chest D-ring need not to be very strong. In fact, quite often (especially for short trips), I don't attach the regulator at all (note that after seeing a picture of me breathing from my stage while scootering, I may change this practice--the regulator slipped on my right arm, away from its normal position). A thin o-ring is easy to break and strong enough for its purpose. The o-ring that I was taking about (and I'm sure it the same thing you are talking about) allows the snap to slide on the hose (at least most of the times ;-). My point is just that there is no reason to put something that cannot be broken easilly.
