This is definitely a heavy oil ball.
I polished mine with Black Magic's "Active Attack" prior to drilling. The ball surface looked too dull for anything in our state.
I've thrown this ball on five versions of medium, two versions of dry, and one type of heavy oil.
On the three mediums, the ball played clean up the balls with a flat-push. It also played a swing shot very well. (The ball bleeds as you get past the 35, but you can spin it more to delay axis migration.)
The coolest thing about this ball: the pseudo-heavy oil.
There's a house on this island that strips maybe once every 4-6 weeks; let's call it Kalihi Bowl. Because of the decision to not strip regularly, the lanes appear to have 58-ft of oil. Not feeling in the mood to point 5-12, I decided to take the Throttle to this shot.
After 15 frames a shot began to develop. Instead of playing 15 to the 13, I was able to move into the 19 and swing out to the 12 board. My friend who was practicing with me commented "wow, there's a shot inside now!"
In any event, here's the can assessment:
Heavy: 22 of 24 cans. (This is the hookingest ball that I own.)
Medium-Heavy: 23.5 of 24 cans. (I think that it would get 24 if the ball had a nicer look on the back. I can't get over it looking like it won't finish.)
Medium: 20 cans. I have other balls that work better for this condition. (Namely the Throttle-R.)
Medium-light: 16 cans.
Light: Don't bother.
All-in-all, this may be the best heavy-oil ball that Columbia has made to date. The problems encountered with prior Columbia heavy-oil balls do not seem present with this one. (No "Roll"-out; no "Arc" in the heads)
If you're looking for an oil ball, buy a Throttle.
