Well, I don't know what you would consider the 916 All Terrain in terms of solid or pearl, but I would consider that to be equal or stronger than the Anarchy.
However, it all depends on the shot shape you are looking for? If you are looking for a ball to just be really flippy at the spot then the Anarchy would be your choice. If you want something that is very angular but still sure footed through the front of the lane then the 916AT should be your choice.
Can't really go wrong with either, but I'd like to see more of the Anarchy on a sport shot. Oh, and at a similar surface the Anarchy is stronger than the Virtual Energy, even being a pearl.
