I've been bowling off and on for over 20 years and always changed my ball surfaces manually (towel in one hand and flipping ball in other).  However, I have heard people in my leagues talking about how they adjust their balls to different grits from week to week.  I know they aren't going to pro shops to do this.  They obviously own a spinner.

Is it worth it?  The ones I saw are around $250.  Are they easy to use?  Would be cool to keep my balls the same exact grit polish week to week instead of paying pro shop $3-5 to get this done.

If your truly serious about bowling you need to think about investing in a ball spinner.  WHY.... please read my post on the Radical Ball Study measuring grit surfaces from OOB, actual grit (OOB) and how quickly the surface changes with as little as 10 games.  If that study does not convince you to think about
investment in a spinner.....well to each there own!

Cover prep is essential.  I'd feel pretty unprepared if I didn't have one.

So do you do cover prep on each ball every time you use them?  Once you find a surface that works for a ball, how often does it need re treatment?  If untreated, is there really a huge difference in reaction?   I'm just wondering what I'm missing by hand cleaning with different scotch brite types?  Thanks!

I recommend to my customers that they touch the surface up by hand with the appropriate medium before every set.  It takes about 2 minutes, but most of them don't do it that often.  --  JohnP

I have owned a Vertex 1/2 since 2009 and have very pleased with it, not a single issue with it.

I'm going to soon!!

Vertex 1/2 hp since 2010.  Best bowling investment I made

vertex I/2 hp had mine about 7 yrs, good investment. word of caution though ,using these on a regular basis does wear the cover down.in my opinion .common sense tells me when you use an abrasive on any surface it will wear it down.
