Ebonite has hit a homerun with the addition of the Game Breaker 4 Pearl. It compliments the GB4 ( & GB3 for that matter) very well. It is clean through the front and gets well down lane before the V2 enhanced core kicks in and drives the ball through the pin deck. It is quickly becoming one of my favorites. 2.48 & 0.048 have always been great core numbers for me and match up well to my speed (16.5 mph-ish) and revs (420-ish). I threw it against another of my favorites, the Brunswick Melee Jab Blood Red. They had a similar shape, but the GB4 Pearl was about 3 boards with my feet stronger and slightly stronger through the pins. This one goes straight into the tournament arsenal.
