i think you went too aggresive on the pad choice. if i'm using OP or OPS i don't go any farther than a white polishing pad. try using the OPS with a white pad. you may have to work it a bit, but i would guess that you'll still be able to remove the swirls this way. about the only thing i use with orange cutting pads are compounds (OC or Pinnacle Advanced Swirl Remover are my products of choice currently).
