To piggyback off of what Timisu stated-- the Reax V2 (solid) is a very strong, yet usable asymmetrical core ball; most of the times, when dealing with a ball that is this strong, anything less than "flood" conditions mean that the ball can't come out and play, so to speak. The Reax V2 takes to surface adjustments better than most balls I have seen; after applying your favorite layout for strong "asym" balls, you'll be able to alter the surface strength to match up with your game perfectly. Before adding polish (not saying that you will, but it is an option)- I would take the surface up to 2k abralon, and then each subsequent grit to find the reaction you desire. Even at 4k (w/o polish) the ball will handle most long/heavier volume patterns, but will give you a very clean look through the heads and mids. (Side note-- the original Reax is going on discontinued lists, buddies has them for $100 shipped right now, and the first Yeti is only $85 shipped now-- the original Reax is more pattern specific (OIL!!), but is one "heckofa" ball)
Also, for symmetrical balls-- if you want something to handle high volumes, grab the unleashed. A ball down option is the grease monkey, original yeti, and also the untamed. Don't forget about the "Torrid" line, with the elite being more skid/flip, and the affair being more "control" overall. Radical has a lot (but not redundant) of options, but each release has a specific intention in mind. I love how they hit, roll, and look on the lanes. When I pick up my Reax, I feel like every shot will be a strike-- I can't say that for most of my other equipment!
