It raises as many questions for me as it answers. (Spine/flo orientation on the adjustable clubs.)
I have often asked my clubfitter to pick a head for me with the specs I wanted, so they turned out pretty well despite not being "adjustable."
My R11s I changed one setting on it when I got it and its been that way since. ONE.
I'm hitting it well enough the R1 doesn't look too impressive.
I was not aware the shaft changes position in the adjustable headed clubs. Only the head changes, that I've seen.
Hmmm... I have the Ping Anser, R11s, R11, Cobra ZL Encore, S3 and the shaft does rotate. It's why so many of these shafts have graphics that go around the shaft now to help cover up this phenomena. Trying to think if the 910D3 I had was the same, but all of mine the shaft changes orientation when you adjust the hosels. It's why I mentioned it.
The Cobra I have the tip set at the neutral location so it's consistent at least club to club if I swap heads and play it in neutral.
I think you'd need two floating cogs on the adapter to achieve shaft/head adjustability that kept the shaft alignment in place. I'm not up on the '13 offerings and if any of them have such a setup. The 910D3 had one floating cog and then the shaft adapter as the second "cog," so I think even that one the shaft moves.
