There are some great comments in this thread. As others have said, your swing seems to be very efficient. I am wondering if that launch monitor is registering low on swing speed, because the balls speeds of 138 to 140 really would suggest a swing speed of more in the 96 range, imo. $400 is not much to some and a lot to others. I probably would spend it if it really gave me an extra 6 yards carry.
As one other post wondered, I, too, would be curious as to the length of the shaft in the F9. If it is longer, than your Rogue’s shaft, then the drivers are essentially identical. I would guess, like others, that with your swing being as efficient as it is, the mechanics are very good and you could pretty easily find another 4 or 5 miles per hour club speed.
