You have to have limped to limp/call. These are cold calls.
Raise on this flop is mandatory, as so many turn cards kill either our hand or our action. I make it bigger, actually. With your call, the pot is $140, so a $60 raise is less than half pot. I go at least $120.
As played, obvious call is obvious. You have a flush against a steaming and wild vilaain and have already committed half of your stack. Get it in.
This is really a question of commitment threshold, rather than SPR. your SPR is under 4, so you usually will be committing with TPTK+, but once more than 1/3 of your stack is in the pot with a made hand, you are almost always right to get the rest in rather than folding.
Especially with the speech, V rarely has a NF here, so really the only hands you're worried about are Q and J-high flushes. Sure, they're in his range, but never, ever, folding here.
