Tanner. I dont know what the differance is but I have the 910Fd. it is the best 3 wood I have ever played. I use it a lot of the T and get great distance and ball control. I also use it a lot on par 5 of the fairway and again it is fantastic. The 910 f is prefered by many because of smaller head of the fairway but for me the bigger head is great of the T and have no problem hitting from fairway. Key is to get the right shaft and then play with the settings. I have added more loft so it playes 15.75 degree loft.
