flopped Str8 on very wet board...turn bet size?

[Skleice]

UTG+1 is Villain $191 - seems decent ABC player
SB is Hero $99

Villain calls, Folded to Hero who completes sb w/ 10 [img]/images/graemlins/club.gif[/img]8 [img]/images/graemlins/diamond.gif[/img], bb checks.

FLOP: 9 [img]/images/graemlins/heart.gif[/img]Q [img]/images/graemlins/club.gif[/img]J [img]/images/graemlins/heart.gif[/img] ($2.9)
Hero bets $2, Villain raises to $5, Hero raises to $17, Villain calls.

TURN: 2 [img]/images/graemlins/club.gif[/img]($36)

I think I'm good here, but what's the best bet size on turn??
