The Bobby Grace 100% Machined from 303 Stainless CROSSBOW with the radial face rolls the ball so early its amazing. The radial face produces such an instant roll that we have engraved the sole with "ULTRA HIGH RPM" (Also known as INSTANT ROLL). The proof is verified by the leading sports software known as Quintic. It measures the amount of overspin (RPM's) off the face. Designed with generous heel and toe slopes, it features adjustable weights and sight lines on the topline and back flange. The tri-plane sole creates very little drag, making putting on the fringe a breeze, and our famous HSM² radial face delivers an incomparable early roll. Dual sight-lines on the top line and the back flange assures you that your hands are in the proper position. Grip is our popular 1.5 Flat Top grip.
