I understand what you mean however I don't know if I would call it consistency when I first started using the Dude it was a little bit to angular and after six games like you say it may just be a little too snappy for the condition so what I did was took off the Polish and sanded the cover to 4000 grit and now it is one of the most predictable balls and Rose controllable balls I have ever thrown if it is getting unpredictable for you try a surface change

Oh didn't see that . I have two dv8 balls pin in ring and I agree with you there. My other two are pin up and they work great for me. I am rev dominant so I tend to require conservation of energy
