I would like this pre-flop steal raise if I knew the CO->BB were tight players. But given your reads, what made you think this was a good opprtunity to steal?

I bet the turn, your hand still has showdown value agaisnt a super loose player, so bet the turn and if your flush misses, you can check behind and take the free showdown, and you might even win it right there.
You won't get checkraised by a super passive post flop player that often.
