Is there a coverstock change I can make to reduce the over/under reaction I'm getting ? I've tried solids, pearls and pearl particles with the same result.

I think the center I bowl at changed the way they oil the lanes recently. All of a sudden I am getting over/under any time I go from inside 10 to outside. Too early on the dry outside boards and I'm high in the pocket or Brooklyn. Left of target skates down and light in the pocket or 3 pin. I can go straight up 5-7 with less agressive balls but carry suffers.

I've tried hand adjustments to take something off the release but that doesn't seem to help - that just makes it harder to get to the pocket period.

Thanks in advance.

Here's one.

A common surface finish for pearl resin balls is 1500 grit US/CAMI polished. A pearlized resin ball can make certain patterns and/or certain release have an over/under affect on the ball reaction. Many people will change the surface of such balls to a final surface of 4000 grit Abralon (use a sequence of Abralon pads to bring the final surface up to 4000 grit Abralon.)

Side note: Abralon uses the FEPA (Euorpean grading system). 4000 grit Abralon is usually called P4000 grit. Compared to P4000 grit, 1500 grit US is approximately P3000 grit.

In any case, a pearl resin sanded to P4000 grit will usually hook slightly earlier, hook slightly more and have slightly less backend, making it less susceptible to over/under and less susceptible to carrydown. Emphasison usually and "In General". It doesn't work for everyone. SOme people require a rougher surface, like 2000 grit Abralon (P2000 grit). Some people require on a lsight hazing of the polished ball with a 4000 grit Abralon pad.

Everyone is different. And this is only only example. Polished solids (resins or particles) can use a similar treatment or MAY ONLY NEED a slight hazing of the surface to reduce the over/under. There is no set or fixed formula. Take everything in small steps because it's hard to go backwards or to start all over again.

Good luck.

Bowlin for Beer,

Charlest has given some excellent advice. I, personally, have certain pearl reactives that I keep on the "dull" side to blend out reaction. One such ball is my Wild Ride.

Then I have others that I like pretty shiny (Rattler, for example) so I see more contrast on the lane. On any given night one is "better" than the other for me.

There is, however, a fine line between taking some "gloss" off the ball and getting them so dull that they lose some of the recovery late on the lane. The more dull the cover is, the slower it's response to friction will be. I guess the point is to not be afraid to make adjustments to the cover (within reason).

I have found that shorter pin to pap distances and surface help me the most on wet/dry conditions. regardless of what kind of cover I'm using

Excellent advice. Most of my stuff is polished. I do have a solid drilled stacked that is somewhat less sensitive, but i will try knocking the polish off my other stuff and see if that does it. Thanks a lot.

for this i find the bo-tie flare track... put each 1 to where there face'n the top my ball spinner then sand with a low grit....use polish after if you need. the idea is you want to sand against the track flare.. it kinda kills the reaction but still carries. you can also sand with the track flare to make the ball hook a few more boards.

I like to use a stronger drill with a 4" across hole (my axis coord 5") 2000 ab surface
