The static spine is .340 and the program gives the dynamic spine as .3557 so, while it says you are shooting stiff the discrepancy is not all that far off. Easton may say that anything from .360 to .320 is fine for that particular arrow. The program seems to be geared toward target archery as opposed to hunting archery. As a matter of fact an arrow will show stiff when you have the target box checked and may show fine when you have the hunting box checked. When taking into account the tolerances that are acceptable then, even if the program says your arrow is a bit stiff, it may still shoot just fine for you. As you know, when you get the arrow in the right spec"range" and the bow in the right spec"range" you still have to tune them together.
