Due to the complex nature of the physical interaction between the various materials used in the core and layer of a multi-layer golf ball, certain advantages and disadvantages potentially offered by certain envisioned designs are: Unpredictable. A core (2) includes an inner mantle layer (3), an intermediate mantle layer (4), an outer mantle layer (5), and at least one cover layer (6), the core having a PGA compression of less than 70, Golf ball 1 wherein the 2 / inner mantle layer 3 / intermediate mantle layer 4 combination structure has at least 30 PGA compression.
