all the shafts definitely need to be completely sealed, finished, cut to YOUR preferred length, nocked and pointed up, before any testing.
the idea is to find a spine that works with yer draw length, so i just cut 'n' point taper to the arrow length that works best for my draw length, allowing for the point taper. iow, i don't play with different arrow lengths - don't want or need that since this is why i'm testing out a fair range of different static spine shafts.
i bracket at least two levels of stiffness above and below the bow's holding weight. i typically get a dozen with 6 different spines, and all at the lowest possible mass weight per shaft.
i leave one shaft bare and another fletched. this becomes a 'woodie kit' that can be used with lotsa bows (at my draw length).
also, and very important! a selection of field point weights is required - i use 125, 145, 175, 200, 250. all points are hot melt glued for easy on/off.
final arrow weight is gonna be based mostly on raw shaft weight and point weight. yer finished arrow length is a constant. fletch and nock weights are minimal, as is finish weight. some woodie shaft vendors are very accommodating with regards to raw shaft weight ranges. i get them as low in mass weight as possible (for any given static spine) in order to use as much up front weight as possible.
i do not care much at all about foc - with woodies, there is much less versatility for tweaking unless yer holding bow weight is at least 60# or more and you find lighweight raw shafting.
