sorry bout the misunderstanding.
I have two Dolphin 2400s
Just put the72 along side of the 2400 for size comparison

ahh, if you want to double them, then double them. No real reason not to. I would double them, put some amount of pressure in them, and hang them in a pool from a luggage scale to get their buoyancy before I dive them though

Sounds good.
Thanks for the info.
