puttnfool Bottom line, Dave says he doesn't even align his shafts. That speaks volumes.
That's not what he says. He says he does not bother aligning shafts with negligible spines.
To him 3 cpms or less between 2 planes is negligible. And he tries as much as possible to order shafts known for their quality. Way back SK fiber made shafts that were guaranteed 360 +- 1 cpm

Shafts nowadays have come a long way but you can still buy an expensive shaft that wobbles.

To begin with, I want to make very clear that I don't think spine alignment is a fine tuning for performance or feel. It is damage control!Spine is a shaft defect. The best answer, IMHO, is to minimize the defect to begin with. Spine alignment is a last resort, IMHO, to minimize the damage that the defect does.
I go out of my way to order shaft models that I know to have negligible spine -- then I just don't worry about aligning. My personal belief is that the threshold of negligibility is probably 3-5cpm, and I treat a spine of less than 3cpm as something I can ignore. Some ways I use to choose shafts:
