The Ebonite Cat Series balls continue to amaze me with great performance and reasonable prices! The latest one to impress me with outstanding performance is the Pantera. I have this ball drilled straight up, off the label, nothing fancy. This ball performs quite well in medium to heavy oil, and has awesome hitting power for pin carry! I am a stroker, and the ball in it's out of box condition hooks too much for me on medium conditions. But on heavy oil, it's a monster. When the lanes are dry, don't even think about using it. It's cousin, the Tiger, would be a good choice in that case. The pin is out on my Pantera, and it roars like a freight train on the backends. The ball gets thru the heads fairly easy, and I like the fact that it doesn't hook early. The ball can be tamed easily by polishing it. It then becomes an even better performer on medium oil. It's a hard ball to put away, once you start continuously striking with it. But when the lanes break down, put it in the bag! I've shot several 680ish series with it. But expect to leave an occasion 8 pin, and sometimes even a 9 pin. Overall, I rate this ball a 9 out of 10. Great ball for strokers!
