To add to Plowboy's review:
The ball is simply amazing as he stated! The combination of the Anger cover and Psycho core is pure art in motion. The motion of the ball is very clean throug the heads, with a solid midlane read and strong, yet controllable reaction off the break point. The out of box 4000 Abralon finish helps it get down the lane without sacrificing ball motion. Hitting this ball with 2000 or 1000 even, will help it achieve a great motion in heavier oil. Powerhouse Factory Finish will help more for the burn.
Layout: 4 1/2 x 3 (pin under ring), very small 1/2" x hole 4.5 inches out on midline.
The energy retention of this ball, even with the more aggressive layout is quite impressive. It turns the corner like a Psycho but has the smooth midlane roll from the Anger Cover (Max hook Reactive). The Acid seems to be about 3-5 less in the front than the Anger, but makes up for it with its strong backend reaction from the Psycho Core. This is a definite fit right between the Psycho and Anger and is in definite contention to be Hammer's Benchmark ball.
If you feel like your psycho is too jumpy off the break, but can't change back to your Anger because it might overreact, the perfect fit is the Raw Hammer Acid!
