When I purchased my irons, I was fitted for them using the Shaft Optimizer. I really love the feel of the KBS Tour shafts, but my distances don't always make sense to me (and yes I am considering solid strikes and not mishits). It seems that as I get into longer irons, I see less distance gained between clubs. Short irons are powerhouses, though. Here are my approximate distances...
PW - 125
9 iron - 140 (sometimes more)
8 iron - 150
7 iron - 160
6 iron - 170/175
5 iron - 175
4 iron - 185
3 iron - 190
The trajectory seems to be about right, but somewhere between the 5-3irons I manage to lose a club of distance. Could I be getting too much backspin with the KBS Tour? Could the Project X PXi take some spin off and improve distance?
I have a fairly quick tempo and load the shaft fairly well.
