First of all,the spine is the most important part of any arrow,it must be consistant throughout the whole bunch.



Straightness means very little but the insert running true with the arrow means everything.This is the big advantage of the Easton Axis arrow.It insures the insert will run true.Also the same design puts the stress in the arrow instead of on the end in a direct hit on the front end.


Easton gives accurate numbers and their numbers are measured using the full length of the arrow minus 2".Not using a 28" span and then adding a little to make the numbers look good. www.eastonarchery.com/products/truSpecs.asp

Now I know this is their sight and they will advertise as they see fit but most that have checked arrows for straightness and spine will usually agree that Easton is one of the best.


Read up on their sight about the Axis arrows.They seem to be advertising what the individuals out their in the real world are saying to be true.I have not shot these arrows but it is looking very promising that I will be in the near future.


Oh yeah,I shot my best scores to date with arrows from Easton that had an advertised straightness of .004 and I also won more money with them too.


Also,the most accurate shafts in the world have a straightness of .002 .Even though there are arrows that advertise .001 but the best in the world don't use them.Think about it.
