Hi Blade,
I've known Jaz for a while, but we never personally met. We were introduced by a mutual friend. Back then I just got my A320 type rating and needed lots of advice on how to get that first FO job without any A320 time. Jaz was extremely helpful in giving me tips and general advice. I finally got that A320 job.
Forums are difficult to judge people. Maybe Jaz was a bit too defensive in his comments to Blade, but all I can say is that he is not arrogant at all. Just a great guy who likes to help out others without even thinking what's in it for himself.
