It's really totally your call, but I think AX is a large enough con that winning your division should be a good sign that you're ready to move up to the next one. What other intermediate awards would you want before continuing?
But then I also just don't like awards-based divisions, especially as it applies to that murky area between "novice" and "master". I've been very pleased since one major group win bumped me up there and I didn't have to think about it anymore.
