If you want to mix it up, I would raise with 78s, not 78o, it is just too weak. Unless of course the blinds are giving their money away.

I think you can get some info on the strenth of your opponents hands on the flop for less money. This of course means raise. If you get a 3-bet behind you you should be done with the hand after an UI'ed peel. After you raise the turn in a protected pot you've shown so much strength the blind is worried about a monster and will go into calldown mode, even with an overpair IMO and experience (this makes the river value bet thin IMO as well, but I think I miss value bets so take this as you will).
