I don't like closing the action on the turn with the nut flush after a bet and a raise. After UTG+1's raise to 30 and SB calls, with $70 in bets that round, why not reraise to 50-70 or so? It really defines your hand, yes, and if your opponents are thinking enough they will fold, but it's a small enough raise that two moderate players who have said they like their hand will likely call it. Then you can bet around 60-70 on the river.

Since you're gonna bet the 40 on the river, putting it in on the turn is like getting an extra betting round.

Other than that, though, I agree that betting the flop is better. Fastplaying flushes works bc everyone sees it out there and the only hands likely to give you action are smaller flushes or two pair or trips before a fourth club hits the board.

Edited because you have the nut flush and not technically the nuts, bc of the SF possibility
