Drilled mine 2 1/2" pin @ 12:00 with a 1/2" shift and pin above the fingers.
Kept this drilling, because it worked well for all X-Factor line balls.
I have posted before, so I won't go through my speed & revs.
Ball react similar to the original X-Factor, hits the same, maybe a little more arc in the back. The first night of 7 to 7 36-38 ft oil and carrydown, I really had to make the ball work. Mover left, slowed down, tried to rev it more, and had the whole lane. After 2 - 190's, I shot 259 after the move.
2nd night of the same pattern, less work involved, but I started immediately to the left about 35, crossing 15 to 5 and back. Had the whole lane, hit the pocket all night, couldn't carry the 1st game for 208, but came back with 257 and a 299. YES!!! I squeezed the 12th shot and went through the face lucky to get 9.
Recommendation - The ball needs hand to throw it, not a strokers ball in my eyes.
Still gets a B+ from me
