[The Gift Of Gab]

What Ray said. After you call he knows you have a big hand anyway, and some flops might let him get away from his weaker hands or at least kill your action.

I'd only think about getting tricky if he was as deep as you were (i.e. I could throw another pot-sized raise at him now or put in a big checkraise on a safe flop.) And maybe not even then; 700 in uncontested profit isn't bad if he folds.
