It wasn't necessarily sarcasm. Cause I think that's what you're saying. And it was a real question, again.. I'm a very casual Archer. When I need to be stuff I take my bow down to a shop I trust and buy what he recommends. So I don't know the answers.
You said no proficient Archer would ever do that.
My question was why not? If... Through plenty of shooting and testing, you find arrows that consistently shoot to the same point of impact.... Does it matter what the sticker says? Especially in relation to an archer being proficient.
I would guess that it would take more shooting and testing to find different brands that shoot consistently than it would to find a few arrows of the same make. So I'm not so sure that proficiency is at question here.
It sounds like he's shot enough to figure out which ones are shooting good for him.
