FYI
Speaking for Doug- fir only.
55-60 lb spine 11/32”diameter 32” long raw shaft , expect a common mass weight of 400 grains +/- 30 grains(11.5 to 13.5 grains per inch). Not quite as common but possible is +/- 50 grains (or 11 to 14 grains per inch). Even less common but do- able is up to 480 grains or (15 grains per inch).
A marked increase in mass weight occurs at the 60-65 lb spine range. Expect the common mass per shaft to be 430grains +/- 30 grains (or 12.5 – 14.5 grains per inch). The same 50 grain spreads still applies or (12-15 grains per inch) but not quite as common.
I’m not sure what a woodsman weighs, nor how much you plan on cutting off or adding back on with your build process , I leave that math up to you, but these numbers should give you information you need to aid in your decision process if you are considering Doug-fir as an arrow shaft medium.
You may want to review your selected spine range if using fast flight string material on the widow. If You increase the spine range of your shaft by 5 lbs spine(60 lb+) it would increase the available mass weight for it on an average of 20 grains per spine group. Ie. It would not be in the “uncommon range” to have available 450-500 grain (14-16 Grains per inch) raw shaft if you selected 70-75lb spine.
As Aromaker pointed out the softwoods recover from paradox quicker than the hardwoods.
Good luck
