I drilled mine with a tall pin (4" above midline) and about 1.5" from VAL, CG in towards grip center, weight hole to bring back to legal, sanded to 1000 grit abralon and then hit with Ebonite Particle Polish. Ball gets down lane and makes a quick little move in the backend, too defined of a move to be considered an arc, but not strong enough to be considered a flip.
One reason to get a polished Pain rather than a Doom is that the Doom is pearl and for a lot of people, shiny pearls can tend to squirt if not drilled for some midlane (myself included). Those people can get a similar reaction out of a weaker drilled, shined solid reactive although without the squirt
