Ok all....I was shocked with this ball! I had it drilled just like my 900 Global Wolverine. Just because I knew the Wolverine would have more back end (which it does) This one...I did NOT alter the surface of this ball. I thought throw the Spectre when or if the oil carries down I can switch to the Wolverine. My 1st night, I took it to league just to throw it for the 1st time during practice. Just to see how it rolls for me. IT NEVER LEFT MY HAND! 1st game 279 (with a 10pin) Series 770. Right out of the box. During practice, it rolled SO GOOD, I never wanted to put it away. It smells GREAT as well LOL!! But man this balls rolls so well. It does not over react on the back ends which is great! I'm going to love this ball indeed!
