Thanks Rico, a good point and I always appreciate your feedback. In this particular case, the ball was an original Inferno that was stacked under ring. I was attending a camp in Texas and heard such rave reviews from one of the students I was bowling with about what a difference it made, that I pluged and redrilled the Inferno to exactly what the OP has on his drill when I got back home. For me, it was a difference compared to what I had before, same house, albeit a week later. TO my eye, I was getting less backend. I totally concur with your thoughts though, it takes more than just my casual observation to definitely indicate the difference. Respectfully though, I still agree with the OP's point...
Thanks
