Take command of every baseline rally with the Wilson Defyer 98 Pro V1 — the evolution of Wilson's cult "Python" project, rebuilt for advanced players who want explosive spin without sacrificing control. At its core is Wilson's new TORQ Shaft , transferring more swing energy into the hoop for extra ball speed, while the SI3D layup pairs a flexible hoop for clean ball connection with a stiffer throat for added power and spin.
