Which jobs are critically manned Air Force jobs right now??

I am going into the air force and would like to get an idea of where shortages lie in jobs...though the recruiter so far seems hesistant to really give me this information. I would like to know where the AF is critically manned so I know which jobs I have a good chance of getting on my contract. Do you know any jobs like this or a website where I can get this??

Please dont give me the www.usmilitary.about.com website.
