Crab - best Degenerative Interface slot?

[Scientist]

I know for the Degenerative slot in the Incarnate system it is usually recommended to go the Core path, for the -HP debuff, rather than the Toxic DoT.  I was curious whether for a Crab using the Arctic Breath patron power, which has double the -resist to Toxic, -40%, it might be worth going the Radial path for more toxic DoT.  Are there any numbers available on that DoT to see where the crossover point might be?

I have the 75% chance for DoT on my widow (T3, zero debuff version) and it's pretty useful. It's about 9-11 damage per tick, usually ticking 2-3 times. Like all the interface slots, it's not spectacular but they stack up pretty nicely over a fight.

I have actually been running the -Hp because it is effectively -regen and -heal since they are both based off HP, either will work but depends on what you need with your build.

I've been experimenting a bit - HP buff for fighting AVs and the damage proc for fighting general mobs seems to be the way forwards. Both on T3.
