I have drilled up a number of the Apex Aggression balls and have found them to be very versatile. Typically this ball flares heavily and is very controllable at the breakpoint, with a strong change of direction and heavy finish, and good at overcoming carrydown. As with all balls, just make sure that you match up the ball with the right conditions. The ERP coverstock is one of the better particle coverstocks which is very friendly to sanding/polishing.
