Multi-layer golf ball construction

A six piece golf ball consisting essentially of;

• I) a core having a center and an outer surface and having a diameter of from about 0.50 to about 1.62 in, a PGA compression of less than or equal to 30, a flex modulus of less than or equal to 15 kpsi, and a Shore D hardness as measured at said outer surface of less than or equal to 60;
• II) an inner mantle layer having a thickness of from about 0.010 to about 0.400 inches, a PGA compression as measured on the golf ball precursor of less than or equal to 35, a flex modulus of from about 2 to about 25 kpsi and a Shore D hardness as measured on the ball of greater than or equal to 25;
• III) an intermediate mantle layer having a thickness of from about 0.010 to about 0.400 inches, a PGA compression as measured on the golf ball precursor of less than or equal to 35, a flex modulus of from about 2 to about 30 kpsi and a Shore D hardness as measured on the ball of greater than or equal to 25;
• IV) an outer mantle layer having a thickness of from about 0.010 to about 0.400 inches, a PGA compression as measured on the golf ball precursor of greater than or equal to 25, a flex modulus of from about 10 to about 50 kpsi and a Shore D hardness as measured on the ball of greater than or equal to 25;
• V) an inner cover layer having a thickness of from about 0.010 to about 0.400 inches, a PGA compression as measured on the golf ball precursor of greater than or equal to 60, a flex modulus of from about 50 to about 80 kpsi and a Shore D hardness as measured on the ball of greater than or equal to 55;
• and
• VI) an outer cover layer having a thickness of from about 0.015 to about 0.100 inches, a PGA compression as measured on the golf ball precursor of less than or equal to 90, a flex modulus of from about 2 to about 30 kpsi and a Shore D hardness as measured on the ball of from about 30 to about 75.
