The new George Slupski 401cc Bang-O-Matic is another size head using the cutting edge design of the original Bang-O-Matic. 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 401cc although it looks smaller than it is. Test results have been excellent.
