Originally posted by BCWV: I, like you, thought I needed one and finally bit the bullet and purchased one last fall. I read where folks said that if you make your own arrows that it was a must have. I checked the spine on just about everything I had and then the new wore off. I haven't used mine for a while. This is just me, but to me, it verifies what I already suspected, kinda like my chrony when I was doing alot of reloading. Just my 2 cents.
