Cluib and shaft comparison: Flightscope data

[GeoffDickson]

Below/attached is some Flightscope data comparing my swing on two different 6 irons and shafts. I think it is a classic example of how a non-elite golfer benefits from GI clubs.

The clubs:
1. Spalding Tour Edition with DG S300 shafts: a classic players iron/blade from circa 1986
2. Ping I20 6 iron with CFS Stiff: a modern game improvement club
Not sure of actual lengths, by TE was 1/4 inch longer than the I20.
Not sure of lofts but TW almost certainly 1* degree less than the I20.

Comments:
Unfortunately I am unable to provide lateral distance or dispersion data...but the disperson was noticeably less with the I20s.
Distance: a few metres further with the I20s
Smash factor: significantly higher in the I20s.
Spin: remarkably similar
Club speed: Higher with the TE. For the metrically challenged, 3.2 km/h translates into 2mph. Would the longer shaft in the TE explain that difference?
Dynamic loft and AoA: both lower in the TE.

My conclusion: an S300 shaft in the I20s might be the best of both worlds.

What do you think?

I don't think the shaft is making much of a difference. Go with the DG if you like better, but the Ping shaft is a good steel shaft as well. Numbers wise you're not going to see much difference either. The differences in your numbers I would attribute almost solely to the loft difference between the two. I don't really consider the I20 that much of a GI club, but by comparison, I can see it getting the label.
