As a Sorcerer, I would pick Bigby's Crushing Hand as one of the spell like abilities. It is a PvP spell, with somewhat limited use outside of it. Now, I do not know if you still cast it 'quickened' due to it being a spell like ability, but even then it does allow you some extra liberty with picking your ninth level spells. No need to pick a PvP based spell. I am not sure if the spell has been changed from OOC. So more questions for someone else answer...
