I would like to be able to store two AP DSMBs with bottles and a little underwater notebook thing.
Sorry, not a direct answer...
2 AP DSMB with bottles is quite a load.
I keep 1 red AP DSMB with bottle in a suit pocket. The yellow one is smaller and CO2 cartridge-filled so goes to the other suit pocket with spare mask, notes, etc.
I found that keeping too much stuffs around the hardness is cumbersome and get tangled with other stuffs (i.e. stages, camera, scooter, etc). Since you only use the blob at the end of the dive, just keep it clear away until then.
The only bag I bungie to the bottom of the backplate is the liftbag for dives when I plan to bring something up, or put on the anchor to reduce pulling effort from surface.
