Spine testing River Cane

I hope this is the right sub to ask this one, but I've been trying to make river cane arrows recently and I want to make sure I'm doing it right. I straightened about a dozen and then spine tested them and they ended up anywhere from 25lb to 45lb, but am I able to skip the straightening step and spine test them before hand? I have over a hundred that my grandfather left for me along with a lot of other archery equipment after he passed, so I don't want to waste any. I live way up north in the US so I don't have easy access to more.
