Which manuscript should I send?

I've had two manuscripts sitting in my Vermont College file, both ready to send as my workshop submission. But which one to send? Which one?
I couldn't decide.

I really want to work on one of them with a college advisor. But do I want to workshop it, too?
The other one was workshopped last March at the novel writing workshop, and has been revised since then.
Should I send that one to get fresh eyes on the revised version?

Well, I finally took the plunge and sent my dog story off to be added to the workshop booklet.
They said we'd get our group's workshop booklet two weeks before the semester begins. Which will probably be after Christmas.
I can't wait to see what the other writers submit.
