50NL Pocket 99's on CO.....correct line? What to bet on turn?

[BIGFISH72]

Villain raises 8% of hands PF(over 240 hands or so). I think its unlikely hes raising 67s in this position.

If we show strength on the flop by raising and then when he checks the turn and river we check, this IMO is such weak play cause we give 2 free cards for villain to hit his overcards. If we bet the turn we shut the door to his over cards. Surely if he has a big pair hes re raising my flop raise? If he has a set, I'm in trouble but I get the info on the turn.

I'm 13/7/3.5 by the way.
