I think I may call here just because you have a big stack for the table and can afford it.. but be able to dump it quick if you don't hit that dream flop.

I generally fold suited aces in the SB when facing a standard raise and a call. I don't think flushes have great implied odds anyway and playing them OOP makes it even harder to extract money. I think you're more likely to stack someone when you flop 2 pair (i.e someone with AQ, AK).

Having said that it does depend on how bad your opponents play post-flop and also in your ability to ditch the hand if you flop an ace and face action. You're really looking to flop at least 2 pair or a gutshot + flush draw.
