Should you adjust your bow to the arrow to get correct dynamic spine or the arrow to the bow. This is for an arrow that you have already purchased using the shaft selection guides.
Hopefully, you haven't cut them or fletched them. That really cuts into your options and ability to tune them to your bow.
Ideally, you figure out an approximate FOC you want to shoot and then buy the shaft that you think will come closest to being stiff enough without cutting much off. You then use a combination of adjusting tip weight, draw weight and arrow length to fine tune it to your bow - done by bareshaft tuning.
Dynamic spine is simply how your bow reacts to a given arrow.
Paul, I would have said the it's how your arrow reacts to a given bow.
