Started the quest for ducting and came across this at the local HD:

Has anyone used this? Picked a piece tonight as a sample and it seems relatively stout although the beads do break up the usual smoothness a bit.
i found several threads regarding 30 gauge but nothing specific to this beaded stuff so I'm seriously wondering....
Thoughts?
