Just drilled a black quantum with a 2 inch pin-to-pap. Ball started with a 3-4 pin and 2oz top.
Ball looks strange, but works amazingly well. Very smooth and predictable, but definitely stronger than the urethane I’ve been trying.
First one I’ve ever set up like this. Shot 680 first set with it, and it should just get better from here as I get more and more used to it.
Won’t be the last one I drill like this.
