Amazing ball. Drilled mine with a 2 inch pin, CG 45 degrees from the pin placed just above my ring finger. AMAZING!!
Can't recommend this ball highly enough, this ball won me a gold medal in China. On the long oil it reads the back ends so cleanly and has enough energy to trip the 10 pin out all day long. I have left the surface with its out of the box lustre.
Looking to bowl on dry or short oil lanes? probably not the ball for you. But any medium house conditions up to heavy oil, seriously consider the comfort zone.
Cheers
