400/800- 100ante- 9 handed

CO (18k) opens to 1800

Button (60-65k) Calls 1800

SB (100k) Calls 1800

BB Hero (14.5k) 7c7h ????

Reads: I was at this table for 2.5 levels- I saw CO open 4-5 pots already at least. Pretty wide range here. Button was a LAG player, opened a bunch and flatted an open a few times, also flatted a 3 bet once or twice. He was in some big pots and played pretty fast post flop. SB was a tighter player than the others but not super nitty. He was on a huge rush picking up a lot of hands. His range is reasonable here since he's the big stack and not a super nit. 

I decided to rip it in with my 77. I feel like flatting will lead to checking and folding on a lot of flops. There's so much out there and I think I have good fold equity in this spot. There's 7k in the pot when it gets to me and getting this through will bring me to 25bbs. And if I'm called and flipping there's plenty of dead money. Is this a standard shove? Thanks for the feedback.
