Tour Edge Exotics E722 The iron features a full-face Diamond Face VFT technology in which 103 different diamond shapes behind the face function as mini-trampolines to create faster ball speeds and expand the sweet spot to outer areas of the face so that the full face of the iron is covered.� The design is a one-piece high-strength steel body with a 360-degree Undercut Design. It lowers the CG to produce a higher launch and increased face flexing, ball speed and overall distance across the entire face. Extreme Toe Weighting achieved on the high toe in the rear portion of the club along with a new toe weighting pocket. This dual toe weighting elongates the sweet spot to achieve a higher MOI and strategic CG positioning right behind center face and further optimizes the sound and feel of the iron. A modern long-distance game improvement iron design that will provide extra distance with the same apex height expected from each iron. The lower and deeper CG allowed the E722 irons to be power-lofted to create distance and lower spin rates, while achieving the same launch characteristics as a standard lofted iron.
