Roll bar main hoop

Does the main hoop have to be vertical, or is it OK to lay it back a tad so it matches the door jamb and post? My 2006 NHRA rule book doesn't specify any angles, but it pictures the main hoop perpendicular to the floor.
Also, what about strength? Some guys think this would make the bar weaker, but we're not talking much angle, and it's supported front and back anyhow.
