With those outrageously low grits, you make me wonder if you are seeing much lighter oil than you think you are and the balls are burning up.
The Hyper Cell is a particle ball, one of the most aggressive balls on the market right now. If you're truly seeing heavy oil, drill it for an early roll with pin and PSA set for that (2.5" pin-PAP, short Drill angle, like 25-30 degrees) and sand it to 500 grit. If that ball doesn't hook, drop your ball speed down to 15 mph or take up needlepoint.
