Suited connectors preflop

[Kristian]

It is a classic move to limp in with small pocket pairs and suited connecters in the first couple of levels.

On occation some jerk will raise you after you limped, and now you have to decide whether to call him.

Holding a pair, you basically have to decide whether or not you expect to gain roughly 8 times your investment when you actually make your set on the flop.

I lack the same type of measuring stick concerning suited connectors. I imagine it is profitable to call a min raise with 8 other players in the pot, and that it is probably unprofitable to call off 10 BB with only the raiser in the pot, but where do I draw the line? It is tough math to do, since it is difficult to define a 'succesful flop'.

Any thoughts?
