Estimating the term…
In a solid golf ball comprising an elastic solid core and a resin cover, the cover has a JIS-C hardness of 50-85, and provided that the ball receives a spin rate S1 (rpm) in the dry state and a spin rate S2 (rpm) in the wet state when hit with a short iron having a loft of an 8-iron or greater, the percent spin retention: (S2/S1)×100 is at least 47%. The ball's spin susceptibility when hit with the short iron is not reduced in the dry state or fine weather, nor is noticeably reduced even in the wet state or rain weather. The ball has so high performance that the ball travels a distance as intended, immediately stops on the green, is easy to control and thus, suited for professional and amateur low-handicap golfers.
A two-piece solid golf ball composed of an elastic solid core and a resin cover enclosing the solid core, said cover having a JIS-C hardness of up to 85, and having a flexural rigidity of 78 (800 kgf/cm2) to 196 MPa (2000 kgf/cm2),
