Update on my humidity problem. First off, thanks to everyone for their help.
I decided the Oasis was shot and got rid of it. For now I am only using the beads and things are better, not great, but better.
With the beads my humidity still seems to "swing" quite a bit. It varies from the low 60's to the low 70's, but generally hovers around the 65% mid point. I don't like the swings, but for now I will leave things alone and see how it goes.
A new oasis may be in my future...
