I'm no tuning expert for traditional gear, but in my limited experience, I don't think the consistency one needs for a compound is necc. It's important, but the whole nature of the beast is different. Most traditional archers are not shooting at quarter sized targets from 30-50 yards and whatnot.
I thnk straightness is still important...but not to the same degree...meaning...I can deal with a little wobble on a nock or point end on an arrow shooting 175 FPS with three 5.5 " banana cuts when you're trying to hit a 4" "spot" at15 yards. Shooting a dime sized spot at25 yards plus with a bow shooting 300 FPS and carbons fletched with 4"vanesis a different story.
Spine I think would be more critical...because of the archer's paradox....you'll see most wood arrow guysthat shoot trad tournamentsare really intomatching spine (and weight) quite carefully...or shooting alum or carbon for greater consistency...anytime fingers are involved...bows get picky...
so yeah it's not *as* critical from my limited experience..however that *doesn't* mean it is not critical.
Perhaps Chad, Arthur and other's more knowledgeable in the trad aspect will chime in....
