PF question: suited junk in the bb vs pfr

[DavidC]

I've had a couple of hands today where I had 53s and T6s in the BB, two loose limpers and then the button raises and sB folds, or the SB raises after the button folds (raiser being either LAP or SLPP).

I folded both, getting 5:1, because:

-The odds of getting a four-flush are like 8.5:1?

-I don't know the odds of hitting the flush on the flop.

-I think I could probably get one of the limpers for two bets pf (mine+PFR's), but I'm not sure about the other limper.

-If I pump this flush draw, it's going to trigger a rake that's going to cut significantly into the pot when I have a small edge (if any).

In the case where the SB is the raiser, I'm going to have to call throughout the hand to max EV, and my implied odds will suffer.

Does this seem reasonable?

Anyone have an answer on the flush / four-flush odds?
