Golf ball comprising a core wherein the geometric center has a hardness X of from about 40 Shore C to about 75 Shore C and the first outer surface has a hardness Y of from about 75 Shore C to about 95 Shore C such that (15 Shore C)<(Y−X)≦(55 Shore C). A casing layer, disposed about the core, is formed from a high acid divalent ionomeric composition, and has a second outer surface having a hardness Z of from about 90 Shore C to about 100 Shore C wherein (20 Shore C)<(Z−X)≦(60 Shore C). Core Atti compression A is from about 40 to about 100; Atti compression B of the core and the casing layer, combined, is from about 55 to about 115 such that 1.05≦(B/A)≦1.75; and the overall golf ball Atti compression is from about 65 to about 120. Also, to methods of making the inventive golf balls. |
