I'd be careful. I just heard a rumor a number of probationary FO's were just let go after failing their probbie ride. Don't know how true that is, but it is in line with them being fat on FO's. If your HI10 doesn't look pretty decent and you have an issue on your ride, might have some issues. But then again, I have no clue how true that rumor is. I heard it from my father's brother's nephew's cousin's former roommate.
