OVERVIEW: Hot Launch E523 is incredibly forgiving and versatile. A super-shallow face and a larger footprint design are made for extreme playability and high-launching shots. The Houdini Sole concentrates mass on the trailing edge to position weight and CG low in the head to optimize launch and stability. Diamond Face VFT creates a series of "mini-trampolines" behind the face for a hotter face with incredibly fast ball speeds and reduced spin.
