Help with orage jacket sizing

Im looking at the alliance and rhyme jackets, they're both "original" fit, not the taller fit like some of their other jackets. Im 5'10, want something that fits just a little longer than normal, but dont want it to be too big and baggy. im thinking large would be the way to go, but if it fits a little longer/baggier than normal id maybe do medium. anyone got advice?
