A big step forward in head design, borrowing from metalwood innovations, allows for a very thin, flexible but strong face capable of generating very fast ball speeds across the whole face. That’s how you get up to 2 club lengths longer.
This club not only generates high ball speeds across the whole face, it’s also very stable and easy to use, courtesy of the weight built low into the rear of the club. Interestingly, this weight port doesn’t touch the face at all, so there’s no loss of face flex in exchange for that forgiveness.
