Wilson Golf C25 Golf Ball The latest edition to the C family of golf equipment, the Wilson Staff C25, a low compression three piece ball delivering minimal spin off the driver, is best matched with the Wilson Staff Ci9 iron. The C25 promotes 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 from long distances.
