    • A thermoplastic multi-layer golf ball has a thermoplastic core center with first flexural modulus and diameter from about 21-29 mm; a thermoplastic core layer radially outward with second flexural modulus; and a thermoplastic cover radially outward with third flexural modulus of up to about 5,000-6000. The second flexural modulus is greater than the third flexural modulus. The core layer and core center specific gravities differ by at least about 0.1 g/cm3. The first flexural modulus is up to about 15,000 psi and greater than the second flexural modulus, which is up to about 9700, or the second flexural modulus is up to about 15,000 psi and is greater than the first flexural modulus, which is up to about 9700, with the first thermoplastic material including an ionomer resin and a polyolefin elastomer and having a 10-130 kg compression deformation of at least about 4 mm.
