I always buy gold series arrows just because I'm that way.
Does it make a difference.......well I still get arrows that just will not group with others.
I'm shooting gold tip triple x for indoor, all are numbered. Arrow number 5 hit's almost a inch higher than the rest. All arrows are within a couple grains of each other. The tips, vanes, and bare shaft were all weight and matched before putting them together and then again matched after put together. The wayward arrow has had the knock rotated and changed, tip changed, has been reweighted and still won't group with the others. Into the junk bin it goes.
So my thought is, if I get one junk arrow out of every dozen gold series arrows, how many junk arrows out of a dozen of second grade arrows would I get?
