Arrow spine question

[Buckeye Trad Hunter]

I have a question about arrow spine.  I believe I read somewhere on here that if your arrows are too stiff that the outside of your rug rest will wear rapidly.  I'm having problems with this.  My rest keeps wearing on the outside and I've already replaced it twice this year
