You might say the new J33 Forged Cavity Back Irons from Bridgestone are "progressive." They include a progressive cavity, a progressive horizontal center of gravity, and a progressive offset.
When we say progressive in this case, we mean that the amount of each of those qualities varies - progresses - throughout the set in order to optimize the long irons' game improvement qualities without minimizing the short irons' scoring role.
The Bridgestone J33 Cavity Back Irons were a collaboration between the Bridgestone design team and the company's Tour players, Fred Couples and Stuart Appleby. This set is, according to the company, the most forgiving iron in the Bridgestone lineup.
"The Progressive Muscle Cavity and Progressive Offset are features that make our new irons great for a variety of players," said Mike Moxie, Golf Club Marketing Manager, Bridgestone Golf. "By giving players forgiveness where they need it most, without sacrificing feel and precision in the shorter irons, we expect these clubs to be a hit with not only TOUR pros, but also a wide range of amateurs."
The "Progressive Muscle Cavity" creates a descending weight concentration through the set from thinnest in the 2-iron to thickest in the pitching wedge. In other words, the cavity is shallower as you move through the set toward the short irons, meaning the long irons have the most concentrated perimeter weighting for forgiveness. And, therefore, the greatest amount of feel and control are in the "scoring clubs."
The Progressive Horizontal Center of Gravity means that the position of the center of gravity across the clubface, from heel to toe, starts out closer to the heel in the long irons and moves progressively closer to the toe in the short irons. This effect gives golfers a boost in getting the face of the long irons squared at impact, while helping to prevent premature shutting of the face with the short irons.
And there's also a Progressive Offset design, more offset in the longer irons (again, giving the golfer a boost in squaring the clubface) and less in the short irons.
The Bridgestone J33 Forged Cavity Back Irons are constructed from Forged 1020 Mild Carbon Steel. All of the Bridgestone J33 family of irons are available in 2-PW with a choice of a True Temper Dynamic Gold R300, S300 or X100 shafts. The clubs also feature a Golf Pride Tour Velvet grip. Custom options for grips and shafts are available.
The J33 Cavity Back Irons will feature a suggested retail price of $899 (steel) and will be available at golf specialty stores and green grass retailers nationwide, beginning in early 2006.
