WHAT EASTON NUMBERS REFER TO THE WALL THICKNESS?
 

HI I SHOOT A 2314 EASTON ARROW CAN ANYONE TELL ME WHAT NUMBERS REFERS TO THE WALL THICKNESS? AND WHICH NUMBERS REFER TO THE DIAMETER OF THE ARROW? AND IF I WANTED TO MOVE UP AN ARROW TO A THICKER WALL BUT SAME DIAMETER WHICH ARROW WOULD I USE? THANK YOU

The 1st two numbers refer to the shaft diameter 23/64"
The 2nd two numbers refer to the wall thickness .014"

You need to reference the Easton arrow chart to pick the correct spine arrows for your setup.. If you wanted the same diameter but a thicker wall thickness.. your'd go w/ 2315, 2317, ect.. But as you increase the wall thickness.. you also stiffen the arrows.

That about sums it up.

I shoot 2314's myself.
Needed to go that big with the O.D. to get 5" helicals to clear a flipper.

BTW, thicker walls not only make an arrow stiffer, but heavier as well.
Wall thickness makes a much bigger difference in arrow weight than arrow length does.

I think 2314 is a decent compromise in that spine value.
Not the heaviest, so you still have a fairly flat trajectory.
Not the lightest with thinnest walls, so you still have some decent durability.
