Does the spine weight of woodies change with use?

[Hawken1911]

I've been practicing a lot for an upcoming bear hunt.  My set-up with cedar arrows gave me great arrow flight originally, but now they seem a little weak.  I'm confident that my form and all the elements of my longbow have remained consistent.  I've noticed the same thing with older arrows in the past, but I've never seen the topic discussed here. I don't have a spine tester, but has anyone else noticed something similar, or have you spine tested new arrows and then spine tested them months later to see if there is any change?  It seems logical that being a natural fiber, and going through the paradox shot after shot that, that the wood could weaken with use.  Thoughts?

That is an intriguing question. I personally don't know the answer. I don't have a spine tester either. I would however make sure that my bow is still set up properly. If your string has stretched it will change your brace height and nock height. Some one else will chime in with the answer to your question.

They may be sucking up moisture... keep them in a dry place for a while.

Typically I don't believe a good cedar arrow will change much if any. Of course today's cedar is a different animal than what I use to use.

I think Mr. Lamb is right. If they are not sealed well moisture could be the culprit.
