When ABLJs first came out our DO considered them dangerous!
We wouldn't let the novices use them in case they cracked the bottle and made a panic ascent.
I've got a log book endorsement from Peter Cornish for ABLJ training. You had to simulate OOA and swap to ABLJ (bottle fed) and swim 2 lengths of the pool breathing off it.
