I haven't fully thought out all the details, myself. But lets discuss some workarounds.
For SW, I think you could reduce the headweight slope. Apparently PureFit sells heads designed for single-length
irons - so this may be the solution to this problem.
Shaft tipping is another consideration. I'm not sure what kind of tipping would be required here - again, largely based on head weight I would figure.
Theoretically, lie angles would all be the same in the ideal set. However, the reason I first started on this fitting line was because I didn't have a bending machine, and didn't want to pay $10/club to experiment. So my original thought was to tip the shafts, put them in the heads, get into the optimum golf stance, then mark where the shaft ends with the toe up (to get a quarter under it). This was my first theory before the complicating factors of swingweight, flex progression. I didn't think that shaft length was all that important - especially as when you figure that at a proper impact position, the centrifugal axis is your shoulder, not the end of the club. The straight line from the head runs up the shaft and up your arm (unless you're flipping or holding the club off at impact). So I concluded that the half inch step didn't mean much.
The other interesting point is that if all the club lengths are the same, then the lies (set at the factory, in increasingly upright lies) will get more upright - forcing you to be more upright. So now we're back to equalizing the lies for
clubs of the same length.
Everyone's thoughts are welcome on the subject.
