Hi Stuart and All,

I have just discovered your article...a bit late am afraid.
First of all let me congratulate you for trying do such a job.

I would kike to discuss your point 8 and to add one

1/ point 8 boyancy

Boyancy is a fundamental safety problem.

you say get more then one source of boyancy, ok but it means also get more then one source of gas to fill the second boyancy mean (second wing bladder, dry suit if it can view as a source of boyancy).

And there we get into the eternal discusion of necessary or excessive redundancy.

A second source of boyancy is a good thing but it should not be here to solve other errors that may turn it it useless ,

among those errors there are :

-lest that can't be dropped and that is attached or scrown down is the shell
-too mutch lest.

unlike oc divers we carry small volumes of gas so we have to be as light as possible and need to be able to drop the the weigth used to compensate loop boyancy in case of loop floading.

one of the means of lightening the diver is to use neutral boyancy spares tanks instead of steel ones (that are used a lot in france)

what I mean is that a correctly and accurately ballasted rebreather diver will be able to go up with a drown loop easily

an heavy rebreather diver even with 2 compensators and 2 dedicated tanks could not managed to join surface emptying his 2 sources of boyancy gas.

2/ to be a good rebreahter diver requires to be a diver not a trainee...

this point seems to be stupid, but it is not, teck diving and rebreather diving used to be praticed only by experienced divers and is now solded to relatively "young divers".

Love of tek gear and tek diving Fashion leads a lot of not enough experienced diver in rebreather diver.

professionnals are also impatient in bringing their clients in this world

Diving a rebreather increases task load, it the rebreather diver can't master the other diving problems perfectly like orientation, boyancy, decompression, used of reels and boy markers and watever

In my opinion a rebreather diver should first be a perfect diver before getting in the rebreather world.

my two cents
