I have recently been given as a present a new Titleist 913 D2 driver fitted with a regular Phanom red dot 70.35 regular shaft The club head is set at A1 and has the red dot weight fitted. I have just changed from a bog standard png K15 regular with 10.5 degrees of loft. What setting would you recommend for the new driver for both weight and head position. Many thanks Fraser Maclean. I have just passed my 70th birthday.
