No, I've never used it with the rebreather - only with doubles. I wasn't trying to say you were wrong - I don't doubt that the wings work better for you. All I'm saying is that the OMS (and presumably other double-bladder, bondage wings) do work in some situations - like my situations - so blanket condemnation is unwarranted. In contrast, I see no reason not to blanket-condemn square lights, or even fuses in lights, based on physics and the stuff I read here. I do not believe, however, that the dual-bladder bondage wings fall in the same category. > If the bands can be adjusted so they don't jam the valve, why don't they > come from the factory configured that way? When I got mine, the bands weren't even on yet - I had to assemble it myself. I don't know how it comes pre-configured, as I bought mine years ago. > If you don't need the 2nd power inflator, why put a power inflator on the > 2nd bladder hose? I do use it because to me, the extra failure point of the extra LP hose is less of a concern than the potential for a primary BC failure, and I don't want to dick around with manual inflation. I was only pointing out that you don't *have* to use a 2nd LP inflator hose, as you seemed to suggest. > Or maybe OMS intends it to be used with a 2nd LP?

Costs & benefits. In my experience, the second inflator is worth it. > If you ask me the likelihood of failure of a LP hose or > cheap plastic valve is far greater than a BC. The BC's never "blow", but the corrugated hoses come out of their fittings - even with triple cable ties. > never a BC failure. A diver with your experience MUST see the beauty of > simplicity.

Unfortunately, I can't free-dive to 400 feet - at least I can't stay down long enough to catch anything. Hence, I choose a complex life support system. The art of all this stuff is in balancing redundancy with simplicity. The rest you gan read in books. I can't use clorox bottles because in Hawaii, unscrupulous fishermen use clorox to poison fish, and I wouldn't want someone mistaking the purpose of the bottle. > I paid several hundred dollars for mine too, and I sold it at a terrible > loss.

Don't forget, I started with single wings - and the layer of dust on them is even thicker than the layer on my doubles. Aloha, Rich
