Take the downgrade. Here's why:
-You've got a grip of TPIC. More so, you've been slogging it out in a crap hole for 2 years, and that should count for something.
-Quite frankly, as far as proof that you're an able pilot, I don't think you've got anything left to prove. Flight instruction, to Amflight training captain, to Amflight EMB-120 FO, to regional CRJ FO, to regional EMB-120 Captain, and all within a span of years that is shorter than many people could handle. You've hurdled multiple types of operations with ease, and if you need another 400 hours of TPIC to "prove" yourself, then there's something wrong.
-Fresno sucks.
-Don't wait to start living your life when you hit "the magical numbers," because it's slipping away from you right now. Miss Chicago? Want to move back? Do it, because life is going to pass you by faster than any of us can possibly imagine.
-Fresno sucks.
-Getting a job is ALWAYS about WHO you know, not what you know or what your EXACT qualifications are. You meet minimums, and you're a cool guy, and you know people. If you can't get a job with your current qualifications, you're probably not going to.
-Fresno sucks.
