Theme of the day seems to be the variables that affect arrow performance. So I pose this question:
I have two different arrows cut exact length and weight same nock, shaft,fletchings(2" blazers) and field point.
One arrow has the fletchings 7/8" from the nock groove and the other 1 1/4" from the nock groove.
Balance point is only a 1/16" or so different putting FOC very close to identical at 11%

What does having the fletchings closer or farther away from the end of the arrow do to performance and flight?

Things that make you go hmmmmm.
