Put them on an arrow spinner just for you, straighter than some brand new carbons I have seen. It's probably an optical illusion because the bag target is curved. Digital camera's add weird effects to straight objects sometimes as well.

And I work at the back of a braze furnace straightening 30 inch long 5/8" dia steel tubes all day on a spinner simular to what you use for arrows. 1,000 to 1500 hot tubes a day. I know bent when I see it.
