Flush draw and tpwk

I've got a good seat at a 9-handed table. Villain 2 is a maniac playing 68/17/1.65 over 29 hands to my immediate right. He's bet draws, raised low pockets pre-flop UTG... he's all over the place.

The other villain is 41/8/0.9 over 36 hands.

Villain 1 (SB) $39
Villain 2 (UTG+1) $49
Hero (UTG+2) $40

Hero dealt J [img]/images/graemlins/spade.gif[/img] Q [img]/images/graemlins/spade.gif[/img]

BB posts $0.5, 1 fold, villain 2 raises to $1.50, hero calls, 1 fold, 2 calls, 1 fold, villain 1 (SB) calls, BB folds.

I considered trying to issolate pre-flop with a raise to $10, but I didn't think JQs was really strong enough.

Flop ($8)
