Hi. I'm thinking about going this route, but for pretty much all of my diving I have to take my kit off in the water and someone lifts it into the boat. This can offer a challenge if the water is choppy, which it often is.
I agree, it is a PITA. I use side exhaust regulators and loop one end of 3/16" bungee around the regulator's exhaust horn and the other end is tied to a trigger snap, which fits perfectly around braided hose. YMMV
