I have had the 910 D2 driver, the 910 F(15), 910F(19) and the Hybrid(21) for six weeks. They are an awesome addition to my AP2 irons, but I have one issue. After six weeks, the metal woods look like I have had them for six years. The finish on the face and sole is wearing off quite rapidly. They are the best hitting set of woods I have ever owned in my 54 years of playing golf, but I am extremely disappointed in their appearance, especially after such a short time.
