Topic: Is it possible to make a batch of hard cane softer?

I was wondering if anyone has had any experience with trying to make a batch of cane softer? I have many pieces of cane at a 12 on the Hardness Tester scale. The cane is too hard for me to make reeds that I like. They tend to sound brittle and don't seem to break-in even after weeks of playing on them. Any ideas?
