I would say that anything below 320 is going to give you some serious sanding lines, regardless of compound or rough buff or whatever finish used overtop. Besides looking terrible, I can imagine it would roll well (likely for reasons stated above). I have used 500 grit abralon (and 600 and 800 grit sand paper) followed by polish. These finishes seem to give a stronger reaction (earlier and more overall hook) than a higher grit finish with polish. The polish does help get the ball down the lane a little easier over the plain sanded matte finish though.
