Spine on Easton XX75 1816 &1916 Aluminum?

[tippit]

I have a bunch off old Easton XX75 1816 & 1916 aluminum shafts.  Does anyone know the spine on these shafts?  I'm now shooting 40# bows so before just buying any carbon shafts or making these shafts up, I thought I'd try to figure it out first (not my usual way     tippit

I shoot a 40# longbow...and 1816's fly great out of it.

Thanks guys...just the info I needed.  I have at least a 2 dozen shaft of 1816, so I'll give them a try after all these years since I switch to carbon.

Tippit, Kystickbow is on with his 40#er and 1816's.   Depending on your arrow length, the 1916 should work with 29" or more.
9 Shocks, remember the newer Easton Charts are on 28" centers for average 29" draw compounds.  An 1816's deflection at 26" centers would be .655 or so.  I guess we just have to try them.

I shoot the 1816's out of my 40# longbow and 43# target bow. I shoot a 28" arrow.
