Best 2nd r3 choice?

zalex

I have a t5cc selector from bg alliance rewards
Im going to fight GM and become TB in a week when some of my team revives will near expiration.
These are my 6*s, who should be my 2nd r3 to help me with act 7, variants, labyrinth etc?(warlock already is r3)
I cant decide between bwcv and ht, but let me know if someone else is worth considering as well

update: i've just got Silver Surfer, is he any good or just rank up worthy for his rating?

I'd say Rintrah
