I have a Pink Widow that got torn up in the pit a few weeks ago. I'm talking multiple deep gouges all over the ball (and directly in my track). The manager said he would get it taken care of. So the pro shop "fixed" my ball. It had to be sanded down quite a bit  to even out the gouges (most of them are now gone), but it came back a lot shinier than before, and it doesn't hook anywhere near as much as it used to. So for the last few weeks I've been using it to pick up the 10 pin because that's about all its good for now.

I have some abralon pads but have been hesitant to use them in the past. But now I've been thinking "I can't ruin a ball that's already ruined". What would be the best to start with? I want it to be closest to the out of box which was 500/1000 factory polished. So I was thinking just straight 2000 grit pad? I have no idea what I'm doing here, appreciate the help!

In my experience--once a ball is resurfaced, it never hooks like it did when new.  I've never been able to replicate the factory finish-I can get close, but all the ones I do, they do go straighter after resurfacing IMO.

It is tricky to get a ball's surface back to factory performance, but I've found something that gets pretty close for polished balls.

1) Reapply the original underlying surface.  So, for a ball that was originally 500/1000/Polish, hit it with 500 Abralon/Slaair, then 1000 Abralon/Slaair.

2) Apply polish, preferably on a spinner.

3) Hit it with a wet 5000 CTD pad by hand.  Takes off the polish just enough to give the ball back its reaction.

Might be more complicated than it needs to be, but it seems to work well.

Honestly EBI's polished surface never quite looked that polished to me, so the 5000 grit pad might make the most sense.
