I read somewhere that wood arrows or shafts are usually weaker or stiffer than the spine weight that they are rated for from sellers. I can't remember which. Anyone help me out?
I would disagree, it depends on where you get your shafts. Yes you can buy "sorted" shafts but most are machined sorted. I've found that some shaft makers will hand pre-sort their shafts to a specific range. Once you have them in your possession I will re-sort and orientate them with a Ram Arrow Spine Tester. The Ram will allow me to re-sort them within a 1/2 lb. of deflection by orientation. The reason I have the Ram is with it's micrometer dial I can rotate the shaft to a specific poundage deflection, mark it and have a set that will spine out almost identical.I read somewhere that wood arrows or shafts are usually weaker or stiffer than the spine weight that they are rated for from sellers.

I have found no easy way to exactly predetermine wood spine needs for a bow. I have accumulated a variety of shafts and will test shoot to see what is needed then order more of what I need.SO, are you all (me being the minority, AGAIN, haha) spec'ing & ordering a 47# spine shaft for a 47# bow? as an example......
Thanks!!Currently, I am shooting 58-59# spine arrows cut a little past 30" BOP from a 47#@30" R/D Omega longbow. I will order 3 dozen shafts of the same specs (55-60# spine all matched in weight) and then break them down into subsets of 1-2# of spine, then tune the bow to that set.
