I'll muddy the waters here. When I bought my first serious recurve...too many years ago to admit...I went straight to wood and started killing game. Back then it was aluminum or wood...there were no carbon arrows to speak about. I simply bought shafts as close to my calculated spine weight/need as possible. I did the whole prep from raw shafts and built them myself. They were fletched with hi-profile x 3.
I have serious doubts about the net benefits of bare-shaft effort. Notice I said 'net' benefits. I think a guy can get close on spine and length (factoring in the known things) and make a very good wood shaft selection. There is no legit reason to avoid woods at the outset, but there is good reason not to jump around from carbon to wood to other. And here's one set of factors why...
A majority of wood shafts have larger OD than the majority of carbons. An arrow contacts the bow in 3 places: string, shelf and strike plate. Compared to carbons, the larger OD of woods affects the actual true nock height by elevating the shaft at the shelf and lowering it at the nock point. I did the measurements and proved it. It's not huge but it will affect flight. The same thing is true for the strike plate...the larger OD results in the arrow (center axis) being farther from the plate. Those 3 alignment changes can really affect arrow flight and make for some WILD times with bare shafts.
My finished carbons were easy to build and heavier than the woods I shot...and shoot. I found carbon arrows to be extremely uniform and forgiving of small errors. Dependable. Low maintenance. Brunettes if you will.
I admit my heart will always take me back to wood arrows. I've found them to require more attention in building, from shaft selection to finished arrow. Grain alignment must be factored. Straightness is important. Nock rotation to get best feather clearance thru the bow...I've found that to be critical with longbows. Woods just demand more of you if you're going to see them at their best. And as I sometimes call them 'redheads'...when everything is where it should be, they are phenomenal.
