100NL HU: top set in 4bet pot

[overun]

Hero and villain have been getting rather aggressive. Lots of preflop raise/fold, mixed in w/ some preflop/raise/reraise/folds.

One hand, hero raises to 3 in SB with Q [img]/images/graemlins/club.gif[/img] 3 [img]/images/graemlins/club.gif[/img], villain reraises to 8 in BB. Flop comes out Q high, villain leads, hero raises, villain pushes, hero calls and villain shows JJ, hero's hand is good.

Finally, this hand comes up.

Effective stacks of about 250.

Villain raises preflop to 3. Hero reraises to 10 with T [img]/images/graemlins/heart.gif[/img] T [img]/images/graemlins/spade.gif[/img]. Villain reraises to 34. Hero calls.

Flop ($68) comes out T [img]/images/graemlins/diamond.gif[/img] 9 [img]/images/graemlins/club.gif[/img] 8 [img]/images/graemlins/diamond.gif[/img]
Hero??

Both have about 215 behind.

What's the most optimal line here?
