The first thing to try with over/under is taking the polish off, maybe take it to 3000/4000 abralon

I average 182 at one house and 210 at another with mine and I am typically a 192 ave.

It's quite clear that it acts like what you have mentioned at my low house which is AMF Syn. 39-40" drier heads, snappy backends and sometimes OB right.

At the other, Brunswick Syn. About the same length, but the ball gets down the lane much cleaner and stores energy and wheels to the pocket like many THS do.

I scuffed mine with a 4000 pad

If the ball doesnt have very many games then it is not in need of cleaning. I would consider going lower in grit like 500/2000.

the thing is i just had oil taken out of the ball. Its got a good amount of games on and its still pretty over under

If you had oil taken out did they repolish the ball?

Maybe they polished it too much?
Dull rarely leads to over/under, whereas too much polish usually does.
