TAKE THE EMB!!!!!!!!!!!!!!!!!!!!!!!!!!!
I've done my stint on the jet and someday I'll head back but not because I'm excited about flying them, the money's better, but I love the EMB! It will teach you MUCH more than the RJ will (stick and rudder, Wx flying because your fly lower, lots of legs, she's old so the automation is the FO, LOL! Etc).
As for training, it's not hard.....................it's not hard at all. It's just a lot of memorization with application. You've been doing it successfully up until now so it shouldn't be a surprise. Just study with our classmates and if you don't understand something...............ASK QUESTIONS either in class, on your breaks or after hours. If you don't then failing is truly your fault. SKW wants EVERYONE to pass and you’d have to be a real idiot introvert to fail out as an FO.
