5 stars. Bought 9.5 degree and regular flex. Previously used Ping G30. Have gained about 15 yards on drives and ball spins much less with roll on hard fairways sometimes giving an extra 25 yards. Dispersion much tighter than Ping G30. Club seems lighter and am able to generate faster club head speed. Slight misses on club-face seem to go much farther than old Ping driver. Great club.
