Product Name: Tensei CK Pro Orange Weight: 60g Stiffness: X Includes Callaway sleeve. Assembled to a length of 45.25 inches for a Maverick Sub Zero. Grip is Iomic Matsuyama model with a backline, installed at the standard sleeve position. Feels more flexible and easier to swing than the 1K series. Personally, it feels a bit like a slightly stiffer Ventus Blue. Feel free to comment regarding price reductions, etc.
