If you have the mins and TSA doesn't do the hire, hire hire...then furlough (I've been warned), then the upgrade theoretically would be quicker at TSA if not for the 1000 hrs of 121 required in addition to their company mins (all intel from other guys). You would hold a line quicker at TSA from everything I have seen (smaller company, typically shorter staffed from what I have been told) than XJT.
