Hmmm, so if I want to change the spine of my arrow, all I have to do is twist the nock. If I twist a 2315 enough, will I get a 2317 out of it???
27 twists will do it........
actually it can work quite well. You are not "changing the spine" but you are changing how the "strong side" of the spine is orientated to how it flexes out of the bow.
Hooter shooters are great for this.
