RE: Spine or stiffness
If you are working within a manufacturer's specified range of arrow stiffness the for hunting your requirements will be met and exceeded.
It is easy enough to bare shaft tune so start with the heaviest most stiff shaft.

RE: Spine or stiffness
I'm sorry, I'm just not getting it. . .
As a performance requirement, I should have also said arrow velocity.
I still don't get how Spine, or bending stiffness affects an arrows performance.

RE: Spine or stiffness
When an arrow leaves the bow it oscillates, flexes back and fourth rapidly. The "spine" will determine how fast that oscillation can be brought under control or weather it will have a negative effect on the flight characteristics.
