Hello gents!

Just a simple question here.
When dualspec comes i plan to have 2 arena builds, one haunt/sl and one meta.

What im trying to figure out now, is what spec will do the best in pve (as meta)

This one http://www.wowhead.com/?talent=IZbxIzsg0qcsguVoE00q
With shadowboltspam

Or another one with Molten Core instead of Imp Shadowbolt and Incinerate spam?
