I dont see how you can ever lay down that set of sixes, unless you get raised on the turn and the river is another spade. You dont make money by making laydowns in enormous pots. I would definately lead the turn. Theres so many bets in the pot, that if noone has the flush even 10% of the time, youre bet was good. If you get raised, its not great, but you were going to draw anyway in this big pot. if you are capping in the that spot on the flop with a hand like Ax suited, with a backdoor straight draw, or KTs, people may believe that you have a flush on the turn(BTW, that is a very good value cap on flop with a flush draw, esp if the preflop raiser has KK, and your ace outs are good). You said the game was loose agressive, dont start laying down big hands in big pots.
