I am looking to redrill my jacked.  I have the stong layout on it with the pin next to my ring finger and the cg in my palm, no extra hole.  This ball does nothing unless the heads are fried, and even then I feel like i have to throw the ball 4 mph to get it to read.  I recently was on pba xtra frame and i asked a question to Jeff Ussery the Hammer brand manager, about his recommended layout for a jacked and he said a pin under the ring ringer and maybe a hole for flaring.  I want to know if anyone has any suggestions on layouts for me... I really like this ball for the price i just feel like im not getting all i can out of it. Thanks a lot everyone!
