Understand your point, but again as I already mentioned dv8's equipment is already clean, and polishing over imo, could backfire, I truly believe that.
With constant designs that Phil and Mo have designed Radicals pieces, you can get almost ANY type of reaction that you seek (drilling on asymmetric, and symmetric pieces, along with surface or polish).
The op will make a decision, but to me this one makes more sense and if safer.
