AquaTec once bubbled...
I am wondering if this is an attempt to just make a name for yourself, being a new diver it is a record that requires no other skill than patience.
As for the hookah. Well that would contradict S.C.U.B.A. SELF CONTAINED underwater breathing apparatus
As for wearing doubles or triples. Considering fatigue I would suggest wearing no more than your thermal protection, possibly a semi dry suit so you can take it on and off as needed. And as for tanks how about 40's something light
You could use a block on your full-face mask and switch out tanks as needed. I would say not to have the tank on your back
