My normal wetsuit (FJ 7 mil) compresses enough below about 80' that I cannot swim up without leaving something heavy behind on an empty (simulated failed) wing. That is tested with just enough weight to ensure descent and a safety stop with an empty wing.
My thoughts on redundant lift:
A) An SMB has the purge valve too high for a controlled ascent.
B) A lift bag without a purge requires a goofy bag pipes style purge on the way up which is difficult to control.
C) A 50lb lift bag with a purge near the top works pretty well and is my choice.
D) Anyone just send up a lift bag and climb the line? That makes me nervous because once the bag is reeling the line out it's pretty much gone if the reel tangles/jams and you have to let go. Plus that skinny line is hard to climb....
