Well, he should have told you that they would weigh more and he was probably assuming that you knew they would weigh more. This is what happens when people assume things..... it makes an
ASS out of
"U" and
ME.
I have customers come on quite a bit with an arrow that I do not stock or is not made any more. I try to get them as close as possible to what they are shooting but do let them know that there will be a weight difference up front.
To be honest though you are both kind of at fault here. He assumed you knew there was a weight difference but did explain that he did not have your current arrows. You said go ahead with out any hesitation or questions.
If you only had a couple of arrows left of the originals I would just make the small adjustments to your sight and chock it up to a learning experience and buy the camo arrows next time you need some.
