The Tour Edge Hot Launch E525 Combo Set replaces difficult-to-hit long irons with more forgiving, higher-launching hybrids, offering effortless performance at the top end of the bag. The E525 fairway features a central rail extending from the leading edge to the trailing edge of the sole, punctuated by a strategically placed weight. This design pushes the center of gravity low and deep in the head, creating exceptionally high MOI and stability while promoting a high launch. Tour Edge's Diamond Face VFT technology, consisting of diamond-shaped, variable-thickness "mini-trampolines" behind the face, ensures ball speed is equally prodigious. The E525 iron is a perimeter-weighted, wide-soled cavity back with strategically positioned toe weighting. In addition to producing exceptional forgiveness and stability, this design positions the center of gravity lower and deeper in the head, allowing the irons to be power-lofted without sacrificing peak apex trajectory. Combine the strong lofts and high-launch characteristics with the iron's 360� undercut cavity, which increases face flexing, and the E525 generates blistering ball speed and massive distance.
