It seems that every time I switch brands or styles of arrows, then the new ones shoot so much better than the last ones. But, in the end, all of the major manufacturers are turning out exceptional quality these days, and I think it's pretty much all in our mind. Barring any spine or weight problems as they pertain to your setup I'd say it's mostly mental. Building a spine tester will show you that most of the brands have pretty high standards. But, since bowhunting is mostly mental, if you are shooting better with the new arrows, then you should definitely stick with them this season! Confidence in your equipment is important when you're aiming at a big doe.
