So is twin 80's DIR "kosher" for penetration?

The right equipment for the task at hand is VERY DIR. Care should obviously be taken that you won't get pinned to the ceiling in a low-on-gas situation, but that's not hard. Diving wet with big steel tanks is NOT DIR. That's outright dangerous for the reasons listed above. The term most commonly used in this scenario is "Balanced Rig".
TO be quite honest, I don't know that I'd be too keen on doing penetration without going dry. A failure of buoyancy would be a real PITA inside a wreck. You could still dive AL80s though as they should provide PLENTY of bottom time for an open water dive.
Maybe one of the real DIR divers or instructors will come by and answer your question officially.
*NOTE I am not a DIR diver, but I am learning more every day about what DIR diving is all about.*

This past August, used Double AL80's 21/35 mix with an Aluminum Backplate, AL40 Deco Bottle with 50%; 1 mil Full Suit with a 2 mil Hooded Vest underneath and 4lbs. on weightbelt --all for a Penetration Class on the Sea Tiger Wreck in Oahu, 120' deep off of Waikiki Beach. Also used an 80lbs. Lift Bag for Emergency/Redundant Buoyancy tucked in MC Pack. . .

Twins are always kosher for penetration.MilitantMedic:
Correction, AL 80s. I remember the big "G" man saying something about only steels only in overhead.

Okey dokey then. You should of stopped while you were ahead.MilitantMedic:
LOL still not answering my question.

Its not that simple.MilitantMedic:
A dive has a plan.
A plan requires gas.
Tanks provide gas.
Tank materials have different buoyancy characteristics.
These characteristics can/could be accounted for by adding weight.
The entire system is more important than the parts.
Blanket statements such as "diving steels with a wetsuit" or any other nonsense has missed the point entirely.
