If you have access to CAB blocks, try putting the Abralon pads in the cab blocks (...oh wait a sec, CAB will probably want to charge me something for doing that). This, along with using the 6-side method, helps to keep the ball "in-round". I would go back and start over using the 500 grit Abralon and work up. If that still doesn't work, you may have to go with something like 1000 grit plus polish it achieve the look you want. I have no idea why it occurs, but I have also experienced a drastic change in reaction when resurfacing certain balls and bringing them back to box specifications.
Another thing to consider is that maybe you are back to the same surface on the BW, but the lane conditions have changed somehow? I had fought with a ball a while back trying to get a similar reaction to "box" and come to find out, the shot I was throwing it on (expecting it to be fresh) was actually bowled on by a number of open players with plastic balls... a huge amount of carry down had set in.. explaining why I wasn't able to get any sort of reaction...

"David Garrard's 50 percent completion percentage means that if he throws six deep balls, three will be caught."
