Hell yeah you should go back to your Hawker 800 SIC gig! The regionals can wait man! Go fly the hell out of that Hawker, have a blast and maybe try and learn something every once in a while. Be advised, flying out and backs from ORD, EWR or DFW all day with an 8 hour overnight at the airport hotel in MEM is NOT as glamorous as it sounds. Aviation, like most things, is more about the journey than the destination.
