Over the last 10 years I have had several driver fittings with different fitters and different launch monitors and I have always gotten the same results that do not match my on course results.
The launch monitor says I need more loft and a stiffer shaft. The monitor says my carry distance will increase by 30 yards. When I take a club meeting the new specifications out to the course it lands in the same place as my old driver.
My launch conditions are 108 mph of club head speed and 159 mph of ball speed with a 9 degree launch angle.
Current driver is a 907 D1 with 10.5 degrees loft and a speeder 757 stiff.
Launch monitor says that carries 230-240 yards when my on course carry is 260-267.
Using more loft on the driver and stiffer shaft gives a much better result on the launch monitor but the same distance out on the course. (The balls of each driver land in the same bunkers.)
Any one have any recommendations?
