I had a chance to demo both the Unreal and the Pure Adrenaline yesterday.
The Unreal lived up to it's name - for a strong ball with surface it made a pretty angular move on the back. The conditions were a little light for that ball to get a great look, but I could still see that it does what it's intended to do. By comparison, I threw the 900G Chemical X right afterwards and that ball was MUCH smoother on the back than the Unreal and, in fact, burned up before hitting the pocket.
About an hour into the demo I tried the Pure Adrenaline and it gave me a great reaction! The lanes were fairly toasty by then, but this ball made it through the heads fairly clean and made a strong but controllable move on the back. This looks like one of those versatile types of balls that has radar for the pocket.
