NIBRAS RAINBOW hasn't fired so far this season, but the handicapper has reacted accordingly (now 5 lb below the mark he won off at Killarney last August) and the 5-y-o is interesting on debut here for the Gavin Cromwell yard. Obama Army has been knocking on the door of late and looks set for another leading role, while the consistent Jackandthefox and Punk Poet also need considering.
