Spines/Bio for max Toxic damage, bad idea?

[Menelruin]

So there are different combos and different ATs for all the damage types in the game, but the only sets that give significant Toxic are Dual Pistols, Spines, and Bio Armor.  Just for kicks, for another "elementalist" theme, I was toying with doing Spines/Bio to try and max out the Toxic damage I could deal.  I've heard though that it tends to be one of the more resisted damage types by enemies.  Would this be a really stupid idea?

Spines deals mostly Lethal damage, the Toxic part is the small DoT effects that the powers apply

Three of the radiation melee attacks deal toxic damage (cone, aura and PBAoE) and the rest deal bonus toxic damage to contaminated foes.

I thought it was Energy Damage?

It's a mix. Some attacks are energy/smashing, some are energy/toxic. The aura and the contaminated bonus damage are 100% toxic.
