I don't know how many compressions sacks you're taking, but I usually keep my sleeping bag segregated. Many times I've ripped down and the tent has been wet. That may seem like splitting hairs, but the tent fly or hammock can dry later rather quickly. The sleeping bag would take longer. I usually take my sleeping clothes and put then in the same sack. That way, everything is together and segregated from smells.

But take my advice with a grain of salt. I'm an over-packer.
