1/2 - Open ended straight flush draw

$1/$2 Normal table with no real maniacs or complete idiot donks in the hand, I pick up an open-ended straight flush draw after 2 limpers and the SB completes.

I hold 7c5c and the board is 6c8cQd.

What is a solid play here against at least one player who will likely bet and then pay me off if I hit?
