Wha?
Organic armor will repair other organic armor components, but why would it ever repair regular sheet metal armor?

If you wanted to mod it to do so, all you'd have to do is give the regular armor 0 or 1 organic regen ability.

In P&N, the best armor is either BioCrystal, or PlasmaProjection (Premium mount). Premium mount PPA gives you the best HP/KT, while Biocrystal gives you a healing crystalline effect.
BCA is nearly immune to small weapons fire, while suffering against Massive damage attacks. PPA has the sheer hitpoints to withstand the Massive attacks, but gets worn down from the small blows.

P&N organic armor will provide anywhere from 5 to 20 HP/KT, depending on the rate at which your ship takes damage.

Unmodded SE4 OA provides upto 35 HP/KT!!! Compare that to 5 HP/KT for the best unmodded armor, and 8HP/Kt for the best unmodded shields.
