Arthur P Most guys don't have a spine tester to check their arrows anyway. The only thing they can go by is how well their arrows group. And as their arrows degrade slowly, their groups slowly get bigger until one day they notice they're not shooting as well as they did before.

Since so many people have spouted the "carbons are either straight or broken" BS, and it has been repeated over and over again, it has become 'truth' with no absolutely NO basis in fact. Listening to that crap, one would get the totally false impression that carbon arrows never bend, never wear out, never change at all.

So, the poor guys don't attribute their poor groups to the arrows. As a result, they start changing the tune on their bows and trying new releases, new shooting styles, all kinds of things. And none of it will do a bit of good until they buy a dozen new arrows to replace the worn out junkers they've been shooting the past 6 months.
