i got the epic battle pro cg ball and believe me there are no advers effects to the ball set up or drilling. the cg is kicked right about 3 inches,but i really love ,mine .this is the second battle i have owned the first one i drilled 3 times and never really liked it.this one is set up with the pin over the ring and the mb is drilled out. it is the strongest ball i have and it is much more versatile than my first. I just ordered a pro cg odessy,(dont tell my wife),so if you throw yours before me let me know how u like it. If it is set up right for your game i dont think you will be dissapointed.
