Underspining is not only frustrating, but dangerous...

After looking at that.... I retract everything I said! That's nasty.

That picture has been around for years and no one knows if it was caused from an under spined arrow. Most likely it had a crack that was not seen before it was shot.

I have shot pretty under spined arrows with no ill effects. I think you would have to be shooting kids arrows out of a really fast bow at close to IBO specs to actually break one on release.

I actually like a slightly lighter spine for target arrows.

That's what I'm talking about. Mans that's ugly.
