Stuggling with mine. Pin above ring finger, drilled strong. I am 14.5 at the pins with about 325-350 revs tweener. Ball just starts up too early for me. Sanded it to 4000 + polish + extender, just to get it down the lane. Mens league night it is only good for about 5 frames, then I can't get it through the heads. Had the weight hole moved from P3 to P2. It is longer, but I really need to keep the speed up. I like to throw between 8-13, but I can't throw Wrecker outside of 15. Did manage to get a good line in a no-tap and threw 31 of 36 natural strikes. Ball carries well, but it is almost too strong for me. 5-6 boards stronger than my Defiant Edge and at least as strong as my Lucid. I may have to plug and redrill it to go much longer. Great ball if you have the speed.
