Trips line against over-agro guy

This was live $2-$3 (I'm posting here because the stacks were relatively deep), and I think villian was a little on tilt. I also noticed that he loved to try to out play people and bluffed too much. He had about $400 and I covered (by a lot). I was UTG and Villian was 2 seats to my left.

Preflop I make it $15 to go with 8 [img]/images/graemlins/diamond.gif[/img] 7 [img]/images/graemlins/diamond.gif[/img]. (this was my standard raise at this table). Villian calls, BB calls.

Flop ($43 after rake) 8 [img]/images/graemlins/spade.gif[/img] 8 [img]/images/graemlins/club.gif[/img] 9 [img]/images/graemlins/diamond.gif[/img]
BB checks, I bet $30, Villian calls.

Turn ($103) 2 [img]/images/graemlins/heart.gif[/img]
I check, Villian checks

River ($103) 4 [img]/images/graemlins/diamond.gif[/img]
I bet $100

What do people think of this line?
