charlest, I did not bring it back to 4000. All I had at the time was the grey pad and a maroon pad, and I wanted to try the ball at a different surface. So I used the grey pad and I was very happy with the reaction I got, so I left it there.
Again, I scuffed it very lightly by hand (don't have a spinner). I have also found many times that balls in the 600-1000 range work very well for me where I bowl. That said, I knew the box finish was 4000 and so I was trying to use very light pressure so that I didn't change the surface THAT drastically, because I didn't have anything finer with which to scuff. Being a novice with changing covers, I don't feel qualified to estimate the final finish when I was done with the whole process, but I think it is safe to say it was somewhere between 4000 and 1000 (I know, wide range).
I was swinging the Widow across the lane, around 35 (feet) to 20 (arrows) to 7-8 (breakpoint), when a couple days before on the same shot I was playing around 12-8 and the ball was struggling to make it back to the pocket. After the soak, I was getting a reaction that was dead nuts on with the reaction I got out-of-box.
