Just wanted a line check on this hand.

Pre: Standard
Flop: CO's raise here is nearly always overpairs here imo, really has so fold equity with flush draws so no need to raise, has very few 7x in his range and 55 will slowplay at a very high frequency. Was debating folding after SB calls because of RIO, but our pot odds are good and we dominated a decent amount of spades.
Turn: Decided to x/s here, mainly due to the reason above. I think villains range is heavily overpairs here and they may be overplaying overpairs with spades, so decided to x/s here.

Interested to hear what people have to say about this, thanks

I think a reg would X turn with an overpair. It's hard for you to rep anything that would CC flop and XC turn, so if he bets into 2 people who both called the flop raise, he should have 55,JJ,Axs. V look like a maniac though, so nice hand.

I'm curious what a better player would say, and his reasoning, but it feels like a bad play to keep calling bets OOP and xs as soon as you hit your Q-high flush.

I would just end hand otf,you have nut flush draws and you range is most likely to have a 7 so no need to call with flush draw that gets dominated so often and our position is bad we cant value bet when we hit because and if turn goes cehckcheckcheck we must bluff into two players with blockers to folding range.
OTT-Your hand is good bluff catcher.
