vilecanards,
No, it wasn't for a 4x4 drilling, but, in any case, that doesn't make it more or less applicable to your situation. Mine was a 4.5" (pin) x 4.5" (MB) x 2.5" (pin height above midline).
At 2000 grit, the stock finish, I could hardly use it in my home house. The 4000 grit, allowed me to use it on the lighter oil (probably true medium oil; the Cell for me requires medium heavy oil, as I have average ball speed.) but the ball hooked so much, I didn't feel I had real control of it.
Don't forget that the finer grit makes the ball go longer IF USED ON THE SAME AMOUNT OF OIL. Under normal circumctsances, it will have more backend, but the question remains as to whether it will go too long before starting to hook??? I can't answer that for you; you would have to test it yourself.
Applying polish is no different than applying finer sanding grits. I wouldn't apply polish to the stock 2000 grit finish. In my opinion, that would go too long. I chose to start at 600 grit, as matter of convenience AND because that is as low as I would normally go, before applying polish. So if that level (600 grit + polish) didn't work out, I'd re-sand it and start over, depending on what the results were. If I want to go back to the stock, I'd just re-sand to 1000 grit, then 2000 grit. Same for a 4000 grit finish: if it was not right, I'd just re-sand it to 2000 grit.
Experiemnt. You have nothing to lose and everything to gain.
Good luck.
