I have decide on 2000 with snake oil for me. I couldn't make the ball a good oiler, so I shined it up for medium heavy with clean backends. This so far is the best reaction I have seen so far.
Use it 2 nights ago at a house which puts out a slightly heavy medium pattern that typically has very clean backends, well the other night it had mucho carrydown ontop of their oil and neither my Swarm or Rattler could make it to the pocket and when it did it was hard to get drive for optimal carry no matter how I rolled it or where I rolled it.
Pulled out the Virtual shine up, moved deep and had tons of room, and it ignored the carrydown like it wasn't there, it was maing a extremely strong move off the break point and carry was very good, other than 2 super smash 7 pins. Might keep it a little longer and see how it goes.
