Don't take comments like that too personally. A lot of senior pilots have been through a lot and they can be a little cynical and likes to make fun of new guys just to break the monotony. Sounds like the CA was poking fun at you to entertain himself. Chances are the CA probably flew the Saab in the past so he knows all about the positives and the negatives of flying the Saab. Every aircraft has good and bad points. The other day, I was on a jumpseat on a NWA flight, and the NWA CA said "you poor slob" when I told him I fly for XJ. I just laughed it off and thought no more of it. You have to grow a thick skin, if you want to stay in this game.
