A thread wound golf ball having improved characteristics of moment of inerti a, spin, and total flight distance, comprising a center, a thread winding layer disposed over the center forming a core, and a cover disposed over the core. The improved characteristics are achieved by shifting the weight of the golf ball from th e center towards the periphery by use of heavy thread. This could be achieved by addi ng a high specific gravity filler material, such as tungsten, to the conventional thre ad compound and/or using polymer materials in the thread that are inherently heavier. By using a high specific gravity filler material, other desirable characteristics inherent in a wound ball such as resilience, controllability and feel, are not affected.
