Easiest way to describe this ball is control.  I drilled mine 5.25 x 4.5 pin above fingers with a small hole 6" over on mid line.  For me this ball needs to have some friction and is more of a 2nd or 3rd game type of ball.  It doesn't like a ton of oil but I'm pretty sure it wasn't built for that.  Now unless your a super high rev guy then it may work a little better on oil. 

Overall if your looking for a nice piece to fill the back end of your back I wouldn't hesitate to put some holes in one of these.  Also got to love an all black ball.  Nice addition to the AMF line.  Please let me know if you have any questions.
