The new Bang-O-Matic is another cutting edge product designed to improve your golf game. This head is cast! Is casting better than forging? No! Just more consistent! With the unique Flow Alignment System the energy transfer is 94% directional energy! This makes for straighter and greater! Bang also added a bit more weight to the hosel for draw bias and a deeper bore. The head size is 460cc although it looks more like 400cc at address. Test results have been excellent.
