Typically I carry the following for a 250fsw ocean dive w/ BT of 30 minutes give or take...

AL 40 with 16/40
AL 40 with 40%
Plus extra 15 cubic ft of 100% mounted on the top of my rig.

Dive buddy typically carries 2 AL 40's with similar mixes

Presumably you're relying on you buddy's bail out too as even running V-Planner on nominal that doesn't seem nearly enough:

1572.8 ltr (56cuft) Trimix 16/40
1635.6 ltr (58cuft) Nitrox 40
978.7 ltr (35cuft) Oxygen
4187.1 ltr OC TOTAL

You need another 10% running at +2 conservatism.

I can't work out how to calculate bailout in the Buhlmann version of Gap I have (I'm sure it's possible) so I can't be sure but I doubt the bailout requirements would be substantially less.
