I have two driver head, one at 8° and one 10.5°
between the two heads I have 5 shafts, the OEM Matrix RUL54 at 46" in S flex,
the Graphite Design Pershing 65 X 46", and Sanvik Titanium S flex 44 1/2",
UST V2 65 S 45 1/2", TTDG S 300 44".
It is very fun with this driver head, depending on the day I play, one of the shaft head combination would be suited better than the rest.
