How do you play suiteded connectors pre-flop?

[GlemZurg]

I'm thinking of the suited mid- and low- connectors from 98s to 32s. McEvoy and Daugherty don't include them in their playable hands and Reuben and Ciaffone cite calling a raise with 98s if the stacks are deep enough.

Do any of these starting hands play profitably? Which ones? Which circumstances?

Thanks,
Justin
