Usually tone 5 octe nas, Prostopinije. Although like Deacon Lance stated, it's written up for every tone.
I've been to places where it's recited. When we start holding hands and swaying to the beat during the Our Father I'd worry, but other than that, recited, choir-ed up, or chanted, it's all good. The best response to what is correct in your diocese/jurisdiction would be to know what the Bishop says about that matter. If he says, "no recited Our Fathers," well, I would ensure the cantor/choir knew how to sing it.
