Stripping off the fletches not only removes the steerage, it also changes your FOC. If you're shooting vanes on your fletched arrows, it changes FOC BIG TIME!
I disagree - most bare shaft tuning is done at 20 yds. FOC IMO will have little impact on flight and point of impact.
I do it - I like it. it will get you real close for the most part. If your form is not good or are struggling with consistancy it may be a futile project. But when done correctly it will get you close.
Of course the final tune IMO should be with fletched broadhead tiped arrows - then just tweak to get it dead on.
bare shaft IMO gives you a much better reading than fletched through paper (wich is IMO a very general description of tune)
