Hey guys. I just purchased a new bow this year and now I have two different styles of arrows. A couple dozen of Easton carbon 400's and one dozen of the new 340's carbon Easton n-fused. My confusion lies in which is the stiffer of the two?

So can you help me out, which is the stiffer of the two.

Easton Carbon 400
or
Easton Carbon 340?

Thanks guys!
