I purchased a new blue hammer 2001. Had the ball drilled 4 inches from my PAP and CG at 4 1/2 inches from PAP. This ball simply would not finish. The house condition that I bowl on is 3-5 units of oil outside of 10 board, 40 units of oil from 10 to 10. I tried rolling the ball around 5 board and the ball still would not finish. I tried another ball with a similar drill pattern and similar numbers according to bowling this month. That ball hooked, so it was not the lane but the ball. I called Faball and explained the situation to them. They told me to ship the ball back and they would replace it with a new one. I just got the new one drilled and this ball finishes very strong, and is very predictable. I could throw the ball outside or inside of 10 and still carry on lanes that had just been oiled for the day. I have only bowled two games so far and had 233, and 255 in out of the box condition. The Ball was drilled almost the same as the first one, the only difference is the CG is placed at 4inches from my PAP. The point of this post is if your ball is not hooking, call or write to Faball and explain what the ball is doing. They will ask you to ship the ball to them and if it does not perform the way it is supposed to, they will replace it. This is the first hammer that I have bought in a long time. The replacement blue hammer 2001 looks like its going to be an excellent ball.
