Should i have second barreled this turn?
Villain was loose agressive preflop (38/24/16), i dont have any reads collected on him

Not that badly played, though I prefer a checkback turn-call river line here

Don't really need to vbet the turn - he may call with smaller flushes but not much else weaker (unless he has some river play). Checkback and he'll bet the river for you

check flop.

Think I like check turn, call river here I think that's the most profitable line.

But if you don't intend to call the river, I don't mind b/f on the turn. Better flushes will probably call, boats will probably raise here. B/F is pretty much the same line as check turn call the river except you get to determine the sizing of the one bet you'll call/initiate.

I don't consider this 'barrelling' in that you have a made flush.

Anyone here think a check turn, bluff-raise on the river has any merit?

dont see how u can chk behind and then call river "always" when he bets because i dont see many hands he turns into a bluff meaning he mostly has sdv hands going to river (except for maybe KQTx with some club blocker and maybe some Ax if hes that type to just turn it into a bluff otr when this particuar turn goes chk chk
