I pulled these off Archery Talk. These charts have been very helpful to me. You really gotta filter through the misinformation when you hunt the web, but these charts have never led me wrong.

I should add to this, a high or left tear could be indicative of a weak arrow spine, and low or right could be indicative of a stiff spine. But your mileage may vary, as they say.

Not sure why Gold Tip took them down. Maybe they are still there, but i can’f find them there.
