I've been having problems ever since it got drilled. According to this and many other sites, the sure strike is supposed to have a great backend. Problem is I don't see it. Instead for me, once it reaches the breakpoint, it completely rollsout as soon as it makes its move toward the pocket, missing it completely. I've tried playing outside, inside, whatever and the same thing happens over and over. I've tried changing my release style and I've been to different centers to see if the oil patterns might be the cause, but that still doesn't work.
I went to my local proshops to see if the drilling might be the cause, but they tell me it's either how you throw or the oil, which I explain above isn't the case.
They also tell me, my drilling is fine and should provide me with some backend. My sure strike is drilled 4 1/4 X 4 1/4 from PAP, which is 5 5/8 up 1 1/4 over. The pin is above my ring finger and the weight hole is above my PAP. I think it might be something with weight hole, since i read it greatly effects reaction in symmetrical core balls, but I'm not sure.
If anyone can help me with my problem I would appreciate it.
