<font color='#000080'>Personally I'd avoid disconnecting things like drysuit inflators when firing SMBs. If it's that much of an issue, get a blowgun. They do the same thing, but you don't risk loss of buoyancy. Or just get another inflator hose from me, and add that to your rig.
This may or may not be DIR, but I think is sensible advice unless you're sat on the bottom, which you can't always guarantee, and often isn't sensible (ie silty bottom etc)
Personally I either use a reg or exhaled air. Depends if anyone's watching.
