Jaded Velium vs Velium Fire

[Aesop]

I'm assuming Velium Fire overall better, but I was wondering at mid levels (specifically 39-50 when my healing is as good as shamans and druids) do you guys think the 60 extra mana is worth the loss of 2 ac and 70 hp from the switch?

Probably a stupid question, the only reason I think it might be is because I already have a ton of hp and AC naturally but a lower mana pool.
