This is an answer for jeepnut and not to the original question.Sorry.


Jeepnut,according to the Easton cataloge that list all their hunting arrows.The Epics are in fact +or-.005(.010" t.i.r.)The Evolutions are +-.004.The only arrows they have that are +- .003 are the ACC and the Kinetic II.


Trust me when I say that straightness is way overated.Heck after an arrow hits a 3-d target a couple hundred times I would bet that none of the arrows that advertise +-.001 will still be within tolerance and they will still shoot fine.Spine is the most critical and weight is the 2nd.

If you don't know already,a hair on your head is .0025 to .003 in diameter.Really depends on the person and color of hair.


I have done some of my absolute best shooting with +-.004 arrows.Definately won the most money with them.
