I don't get it..... You are basing all of your info on right now! By the time you even get to an airline it WILL be completely different! It kinda seems like you asked a question but don't want to actually hear the answer! Who cares what regional is a good choice now! You have a long ways to go! Have you even started instrument training yet? You'll end up with 250-300 hours by the time you're done training then you still need 1200 more.... You're way ahead of yourself, I can't tell you how important it is to focus on your training first! You've got soo many check rides and written tests to take still...and then maybe instructing and staying alive!
