RE: Importance of bare shaft tuning?
bare shaft tuning is really about finding the right arrow spine.something that is more critical for a finger shooter due to paradox or bending of the arrow when shooting fingers.especially with a non centershot trad bow off the shelf.With a release aid and a compound you have more leeway in arrow spine.One of the best ways to do it is to shoot groups bare shaft and fletched and dial the groups together.The same way you would group tuning with broadheads.You should strive for a slightly weak arrow because adding fletching will stiffen the arrow a tad.
