Hi- I'm a 1.0 index- for years this has been my go to club from 110-125 yards. It provides a ton a variety in terms of yardage, flight and control. Last year with the pending groove change, I decide to buy another to have a back up. I recently put the new one into play and cannot replicate the previous distances, I'm max'in out 10-15 yards less. The shaft length is the same, loft and bounce are identical.
Does anyone has a similiar experience and a possible explaination (club head material, shaft stiffness, flex/kick point, getting older....)
