[5NL] 77 flop an overpair in 4 way pot. What to do?

SB - 46/33/11 through 118 hands. Fold to cbet 63%, 5/8. Had notes that villain was passive, c/c 3 streets with a set. Had also seen villain 3bet with KK and 3bet with 65s before calling a 4bet.

MP - 34/32/13 through 51 hands. Fold to cbet 100%, 1/1. Had 91% cbet, 10/11.

CO - 86/0/0 through 30 hands. 56% fold to cbet, 5/9.

Pre Flop: (pot: $0.07) Hero has 7 7

fold, MP raises to $0.15, CO calls $0.15, fold, SB calls $0.13, Hero calls $0.10

Flop: ($0.60, 4 players) 6 3 2
SB checks, Hero bets $0.60, fold, CO calls $0.60, SB raises to $1.90, fold, CO calls $1.30

Is this a good spot to be leading out? If it is, what size should our bet be?

I figure we probably have the best hand on this flop and seems as we don't like many turn cards we are happy to take the pot now, which is my reasoning for leading out.

Or is it just simply call to hit a 7, if we miss, c/f?

Seems to be a spot that's coming up more frequently so thoughts and opinions appreciated.

Found a similar hand, completely different villain though, putting it in same thread.

Villain is 18/15/5 through 194 hands. Fold to cbet 50%, 2/4. No notes on villain, so haven't seen him get out of line/do anything crazy.

Same as above hand, I figure I probably have the best hand and I am happy to take pot on flop. I also doubt that this flop has hit villain's range, so unless he just flat called with 99+, I am in pretty good shape. When he calls, the turn is one of the few cards that I don't mind and decide to bet again taking pot down.

Thoughts?
