Drilled my avenger with the pin 4-1/2" from axis and the cg4" from axis,leaving the factory finish on the ball,without a weight hole.Ending weights are 1/2 ounce positive side,3/4 ounce finger,and 7/8 on top.On our early league condition which is pretty well blended across the lane with fresh backends,I could not believe how deep I was able to play with this ball,and still have recovery in the backend.And I didnt have to throw it to the track to get it to recover.On our late league condition,which is a bit choppy with some carry down,the ball still enables me to get way inside and still have it recover,and hit.As the night progresses,and the heads start to go away,it does stand up way too early,which I may address with a little shine,but for now i will just put it away and pull out something non-particle to get through the night.Will postagain if/when i decide to alter the surface.If you are looking for something particle to enable you to move in,where not too many guys are playing,this ball is a must have.
