Potsize bet at Omaha/8. What to call whit?

[Omaha8Player]

This question assumes a loose game whit bad starting hand req. among the other players.

Hand value goes pretty close in value in O8 that is way there is not that much preflop raise I have read (maybe this is more true in limit, but anyway). So when can I call a good solid raise fore about 4 BB preflop? What hands do I need?
I know this will wary under different positions in regarding me and the raiser and how many players there is left in but I hope this will be an of to start the thread.

Best regards F
