Has anyone else noticed that Easton's arrow spine selection chart seems to result on the stiff side?
I've changed arrows a couple of times over the years, and set up stuff for friends, and I'm noticing a pattern.

It doesn't seem to matter what weight, arrow length, pt weight, or whether the shooter uses fingers, or a release.
I've even purposely selected arrows on the weak side of the spine class that the chart indicated. Still stiff.
A bare shaft hits way left, and paper shows a big right tear.
Sometimes, I can correct it by adjusting stuff, but then it's way off center and the sight pins end up pretty close to the bow.

Glad I didn't buy a whole dozen arrows this time. Got smart and only bought 2.
