From the 737 to the 747 Learning Curve

Hello All!I'm sure that many, if not most of you PMDG 747 owners came to the 747 with many hours racked up in the PMDG 737. I've been flying the PMDG 737 for quite some time and enjoy it immensely.In fact, I've had success and my share of time in the LDS 767, PSS Concorde, the Wilco ERJ-145, etc. The only plane I "didn't quite get it" with was Ralph's Panelshop 747-200 for some reason.Anyway, may I ask what kind of learning curve did you experience going from the PMDG 737 NG series to the PMDG 747? I've been sitting on the fence for some time while feeling that this is something that I should indeed be experiencing.Also, I seem to gather from the product page that I could have a panel state saved, let's say, right after engine start, and start my subsequent flights from that point in time. Time is often at a premium. I'd hate to spend all the time I have to fly on the ground starting the engines each and every time.Thank you so much!Ed Lin, D.O.S.
