Definitely a heavy oil ball
solid symmetric piece, arcing and predictable
i was using mine on a 47' sport pattern last night
its pin up and rollls great
if its heavy oil, you most likely would have to square up and play straighter to start
2000 dull is the OBB finish, keep the surface clean and it will perform well for you

notice in the BTM review, the testers rated this ball highest on the heavy oil pattern
i actually have mine at 2000 + polish.
I am learning more about my game and trying to become better at rolling the ball properly which allows me to use less surface (sometimes)
to much surface runs the risk of burning up the heads on the surfaces and patterns I see.
Good luck, you might want to do a resurface if it has alot of games on it

I have changed surface on Disturbed 3 times.  I also have used the ball at 7 different houses since I bought it. Some wood,some synthetic. There has been oil at some of the houses and the ball still either jumps through face or limps to pocket. I never have bought a dud before but this ball sure seems like one to me. For whatever reason I just don'y match up with this ball. Going to my pro Shop Tuesday and have Jack Jurek watch me throw it and see what he thinks. He said he loved his 1st one but didn't like the 2nd one he got. It happens!! I know Roto Grip puts out some great equipment but this one is not for me.

AGREED!!  I am just way too stubborn some times!! I usually can fine tune a ball and get it to work but not this one. 

Thanks!! It happens sometimes.  You don't always pick the right ball. 1st miss by my pro shop guy in many years. He is only human. Practicing with him Monday . He wants to see ball movement. Talking about changing ball from 4000 abralon to 2000 polish. Maybe even 3000 or 4000 polish before I give up on ball. If that don't work I give up on my Disturbed.
