I got to throw my Xception for the first time today. The local pro shop guy immediately noticed that on the backend the ball set up with the thumb as the PAP. I later switched to my 5.0 and it was VERY noticable on that ball. When it made the turn, you could clearly see my yellow slug spinning. I have never seen any balls do this before. Both are drilled similar, with the MB in the strong position and weightholes in the thumb positive quadrant. The only difference is the pin on the Xception is above the ring, and on the 5.0 it is below it. I was just curious as to why they roll like that, and what good, if any it is. Thanks.
