The new Ci9 iron features improved mass distribution by positioning a hidden rear cavity exoskeleton which pushes weight to the heel and toe creating higher MOI (moment of inertia) and more stability. The distribution of weight also maintains the center of gravity directly behind the iron's sweet spot for solid feel and power.
The Ci9 iron is created from soft 431 stainless steel material and features a one-piece Soft Response Insert that extends across the entire iron cavity. The Soft Response insert creates a satisfying sound at impact and a more solid feel, even on off-center hits. The Ci9 irons are available with stock FST Step-Less steel shafts or Aldila VS Proto ByYou graphite shafts. The new FST Step-Less steel shafts are lightweight and designed with a new step-less barrel to deliver consistent flex and feel with the appearance of a rifle Project X shaft. The Ci9 irons have modified U-grooves that push the maximum limits of the new specifications required by the USGA and R&A. A strategically positioned higher center of gravity delivers a higher spin rate and promotes the ability to work the ball more effectively.
The suggested list price for Wilson Staff Ci9 iron is $799.99 for steel and $899.99 for graphite and includes a 4I-PW, and GW.
New Wilson Staff Three-Piece Low Compression Golf Ball: C:25 Golf Ball
The Ci9 irons are matched with the corresponding crossover, or 'C' golf ball, the new Wilson Staff C:25, a low-compression three-piece golf ball delivering minimal spin off the driver. With the new USGA and R&A groove rule soon to be in effect, Wilson Golf introduces Traction Control Technology (TCT) in the development of all of its new golf balls. TCT is designed to improve stopping power into greens, better carry distance through higher spin production and reduce fliers from the rough by engaging more contact with surface area and grooves. The C:25 utilizes Traction Control Technology to promote progressively higher spin as the player approaches the pin for shots inside 150 yards. The golf ball features a 302-dimple pattern to provide high lift conditions for more height on tee shots and long distances. The suggested list price for the C:25 golf ball is $34.99
