Here's a hand I didn't play the other day, but have been thinking about none-the-less. After calling this flop, are we still strong enough to raise the turn when the straight comes?

Villain is a future version of FTR TAG seven-deuce and will probably fold less than TP or strong draws if we raise the flop. He probably valuebets/calls/folds/bluffs at exactly optimal frequencies. Is our turn value raise range just 9Ts?
