We can all agree that spine does matter for both safety and performance but does arrow straightness really matter that much. Most of the major manufacturers produce .006,.003, and .001 versions of their arrows. prices are exponetially more for the more "straight" an arrow shaft is.
Gold Tip has the Velocity Line that I find shoot nice out of my bow
The Velocity Hunter = .006 = $70/dz
The Velocity XT = .003 = $90/dz
The Velocity Pro = .001 = $130/dz
Is a straighter arrow worth the extra money?
