I haven't thrown one, but I would say, unless extreme drilling and cover prep is done, the Smokin' is not at all for heavy oil. Some people debate whether or not it's even good for standard mediums. I wouldn't advise trying to use the Smokin' on heavy, as there are many better options better suited to do so. However, if you are going to insist on trying, I would look into a very early-rolling drill pattern and a very low-grit cover prep.

Hallelujah!!! SOMEONE AGRESS WITH ME!!!

The smokin is NOT a heavy oil ball what so ever. I use it for the broken down, more drier conditions. it seems to excel between dry and medium conditions. If you use it the heavy oil, it better be a spare ball. . .

Its hard to play with an inferno and not get burned. Last time I threw my inferno, the opposing bowler definitely got burned.

Since I only throw Infernos, just call me the Flamethrower.

The Smokin hated oil and carrydown for me. When it found dry it was a great ball, but just a bit too conditional and unforgiving for me.

cheers lads ill be steering away from that then.
