I bought this ball from ebay from a regional touring pro. I'm a pretty new bowler and I bought it to replace the urethane starter ball that I have. The pro had had the ball drilled with a leverage drilling, 3 3/8 x 3 3/8, with a weight hole on the PAP. I had the thumb redrilled but did not change this drilling layout. The place where I bowl has medium to light oil, all the way out to the three board, with a length of only about 31 feet.
I'm a low speed and low rev bowler and this ball rally gave me an angle to the pocket which I could not achieve with my urethane ball. The shot that I played with the urethane ball was a down and in shot on the first arrow. I tried this shot with the Ti Messenger but it went WAY brooklyn. What turned out to be my best shot was to start in the middle, about the 21 board and aim for the 7 board just inside the first arrow. When the ball got through the oil it rolled like one of those trick golf balls that are designed to roll crookedly, but it broke toward the pocket. It was actually quite controllable, though.
I had read in the promos for this ball (or perhaps one of the reviews on this site) the claim that this ball doesn't leave corner pins. It does. (Not any more than my other ball). With this drilling it was absolutely IMPOSSIBLE to pick up the 10 pin, however. I eventually grabbed a house ball to throw at spares on the right hand side (I didn't have the urethane ball with me).
Like everyone I think I want to stand left, throw right and have the ball come back to the pocket. I still couldn't do that with this ball, probably because of my low revs. When I tried to do this shot, the ball didn't come back to the pocket. Consequently, I'm guessing that this wouldn't be a good ball for the heavy oil.
Nevertheless, the stronger angle to the pocket that I can get with this ball gives me potential for a lot more strikes. It took me 8 games of practice to really find my shot, but I finished with six strikes in a row (the best ever for me).
