I have a post on here where I talk about polishing my levrg.
Normally i'd say find an awesome finish, it gave me added length with amazing back end finish.
However, now that I've polished my LevRG I've shot 717, 703, 757 over three consecutive nights of league.
The polish gives me the extra 5-7 feet of length that I need but it maintains it's smooth strong arc to the pocket. This is one of the few balls that polishing doesn't give it an angular breakpoint shape.
If you loved the levrg and would like to play that same line for all the games in one night then I highly recommend picking up another levRG and polishing the surface, you can keep it at 1000 grit, that's what I did.
Hope this helps!
