My suit has a swivel on the addition valve. I can unhook the drysuit inflator hose, and attach my bc hose with a few inches to spare as long as I rotate this valve. I too was advised to shorten my bc hose and corrugated hose and did. But I found George's comment that you should be able to reach both the addition valve and the bc inflator in the same hand more important, so I did not shorten it so much. >As for the opposite, why would you ever disconnect your drysuit hose and >attach it to your BC? It's much faster and more straight forward to just >orally inflate in the event that your power inflator fails which is what my >first response to a power inflator failure would be.

Heck, oral inflation >used to be the ONLY way to inflate wings and drysuits. > I agree that orally inflating your wing is much easier, but I have yet not found a way to get my lips down to my drysuit addition valve. Some of the caves here can go from 150 to 70 and back, or 110 to 30 then back to 90 (two quick actual profiles). If I did lose suit inflation I'd like to be able to get through these without pinching off any body parts because my suit didn't have enough air in it. I don't expect to ever have to do it, but it is a part of the overall plan. Regs do fail, hoses fail, and I could even misread how much argon I have in my bottle (although I'd steal some from my buddy at deco). I will say one positive thing about the air II type devices...If you are trained OW with one, you learn to donate the primary without any qualms. Other than that, they are pretty worthless.
