I'm with you Cecco - Ample. I had a command on a jet heavier than a G550 with little more hours than that.
Of course you have to watch them like a hawk when they start with 200h in their book, but by 500h, they are well up to speed. Much better than hiring some oik who makes the bosses eyes roll, or some guy with loads of low quality hours, who reckons he's ace of the base.
