Playing SB with Limpers

Assuming 100bb stacks 6-handed, what hands can we complete the small blind with an obvious +EV scenario against 1 limper? 2 limpers? 3 limpers? Let's assume (to simplify some math) that the player to our left is raising from the BB with 10% of hands in all cases, and we're always folding our hand to the raise.

I know a more aggressive way to play better hands like J9s or 65s is to raise from the SB and try to take it down on the flop, but to balance things sometimes we should call with these hands (I think?) and this is the scenario I'm considering for this post.

I've been looking at some stuff on the common flop odds page, and I've run into a problem I'm not sure how to solve.

Let's say we're looking at the case of playing unsuited connectors in the described scenario. Well, we have about a 10.4% chance of flopping an 8-out straight draw. I noticed that I really have no clue about how to quantify that draw (especially way out of position).

So now I'm a little stuck. :?
