just received my new pured golf shaft with a TM adapter and I am not sure how to align the pure line to the dapter.

install the adapter in the head at the settings you desire (loft/face angle, etc)
put the shaft into the adapter with the PPOP decal at the 12:00 position
mark the adapter and shaft with a sharpie with a line (alignment mark)
remove adapter, insert the shaft into the adapter, align the shaft with the sharpie line when you epoxy it.

not sure about taylormade, but some drivers with adapters, if you change loft/face face angle the
shaft will no longer be in the ideal position and you may need to remove the adapter and reinstall.
