What a fantastic piece of equipment. We had our Championship roll off this past Thursday. I drilled up a new Melee. This ball is so smooth off the spot it's unbelievable. Drilled with a 58x5x60, this rock rolled so even through the front of the lane and was very smooth but hard off the spot. This ball hits really hard considering the core design and the performance possibilities of a symmetrical piece such as this. It's the best down and end piece I've ever had the pleasure of using. I left only 5 corners all night long. If you haven't given yourself a chance to use one of these, you're limiting your scoring abilities.
