Hi,
Preflop is fine i'd call too, and so is the 3bet/fold line.
That's not really a prime flop to c-bet but i still think with 60% he's c-betting air sometimes on those boards, and given how ugly it is he might even might a fold with one of the worse overpairs figuring it's just not worth the trouble if he's flipping at best.
Bet/shove is okay too since he doesn't c-bet all that often, but i don't really think that guy would/raise fold anything. More like he would call your donk with medium overpairs and fold only on a scary turn, and raise/call the biggest overpairs, so there isn't much of an upside unless you're trying to be hard to play against.
Hope it helps.
