I am 75 yo golfer who plays to a 9-10 hdcp. I have lost clubhead speed (88-90 mph) but still hit the ball solidly most of the time. My tee shots take off like a rocket but just seem to climb too high. The ball carries about 220 yards but with very little rollout. I recently made up an M890 driver (10*) with a Kuro Kage Black HBP 50 gram (reg flex) which is supposed to give a mid launch trajectory. I LOVE the feel and sound of this combination but feel I’m loosing 15-20 yards because of the steep decent. I have tried changing ball positions and teeing it lower with no success. I average 10 fairway a round so I don’t want to loose that. Is there another shaft that you would recommend for a slower swing speed that would keep the flight lower?
