I'm interested in this as well, as for some reason in my local area they insist that SMB's have 50# of lift in order to do the deep diving courses. I guess they rely on it as an emergency buoyancy device.

some agencies are pushing using a smb as emergency buoyancy. I personally think that's not so smart.. Fun skill to learn but when the REAL SHTF it wont work. A balanced rig you can swim up at all times or REAL redundant buoyancy (Drysuit or even the non Hogarthian/DIR double bladder) is a much better choice IMHO
Then buy a lift bag of 50lbs with the dump/opv at the top.
I heard there might be a Black Friday sale for HOG
