Just bought this ball Friday, 15#. Drilled it up with a modified version of suggested drill pattern #3. Pin is approx. 1/2" below and just slightly right of the ring finger, bomb is stacked at 12:00. This puts the CG directly in front of the thumb hole, no extra hole required. Balanced out just fine, well within ABC tolerances. Anyway, figured it would rev up early and hold a tight line for when the heads burn up. That it does on synthetic lanes. Found out last night, it does not work the same on wood lanes. There, it goes long and turns hard. Had to maintain about 17 mph 12-7 to keep it right. I must agree with everyone else, this ball looks really cool going down the lanes, but I did not think it would hit that hard. Carried the corners well, most of the night. Slightly unforgiving if tugged or sent wide. Had about 3 boards of area to work with. All tolled, a good ball, way too expensive, but the hype Ebonite put on it prior to release was close. It will hook out of the house depending on how you drill it.
