Take a look here as I throw Roto Grip's new Idol Pearl, the definition of a benchmark ball. The smooth transition from mid-lane to back-end makes this ball very predictable and versatile on many patterns. I am using a 5x3x4 layout out of Roto Grip's symmetrical drilling guide. if you have any questions throw a comment in and don't forget to subscribe!
