When you receive a Pured shaft from the Golfworks, the line on the label should be at 12 Oclock, it is put there to make alignment easy. Hope this answered your question.
I had the same question for Club Champion after they fitted me for a new driver shaft that was pured, apparently the sticker is directly down (bottom) when addressing the club.
Be interested to know if this is how Britt & company approach this.
