I usually try to stay away from these as I'm not entirely sure I can attest well enough to that question, being i'm not the sharpest tool in the shed.

However, when presented with this type of a question I always ask myself....wouldn't you rather have the guy who regardless of thier TT or ME time for that matter would perhaps be.... humble?... Dare I say get out of thier seat if only to drag one more gate checked bag down to the cargo loading guys just because it's a nice thing to do?

Somebody who when given a hold can subtract the reserve(+ALTN) fuel from the FOB and give you a rough estimate as to how many minutes of hold you have left in you without scrambling an FMS keyboard for that?...

Wouldn't you rather have the guy who would say heck I'm not sure, but I do believe it's this way or the other... and then give you the leeway to think and maybe even do what you think within given parameters (read safety margin) so you could actually learn in a good way and not by being yelled at with no reason and without even seeing the results of your decision? (FOs and CAs alike...)

Finally, I would rather fly with the one who can do all of the above and in the worst morning, a reduced rest morning after 5 legs the day before and before 4 long ones today could get into his seat, do his job quietly, in a humble way, be patient with me and then just then, smile and adore a beautiful sunrise on the horizon and be thankful we all have jobs and ones that we like.
