Have a Dunlop XXIO Prime driver 9.5 deg head – stock specs a SP-800 CARBON SHAFT
Weight (g) Flex Bend Point Torque
SR 40 Mid 6.6
R 38 Mid 6.7
Which graphite type shaft would you recommend in R?
That XXIO driver has a heavier head and a counterweighted shaft. It will be very interesting to hear of your results. I know those shafts were specifically made for that head. Please keep us posted.
