Well gosh, I don't know why they would be....You use the same jig, same clamp, and use the same hash mark on said clamp.......I'm just not sure how that equates to them being in a differnt place than 4" vanes.......Or, perhaps I've done the folks at the shop an injustice by building their arrows wrong all these years........

With the vane only being 2" long, there is a bit of an optical illusion going on......
