To TaylorGirl,
FYI, I have edited my original version of this post below for accuracy!
The Grand Auditorium Aerocase had been verified to weigh 9 lbs by a fellow Taylor owner who just received a new one and weighed it.
I just weighed my genuine Taylor Grand Auditorium Hardshell Case, and it was roughly 10.2lbs empty.
To quote exactly from the Taylor website the description of the Aerocase: "...its material construction is less than one-third the weight of a hard case."
Now, don't get me wrong, I'm not knocking Taylor. I love their guitars (I own two of them) and I actually own the GS Mini Aerocase. The GSM Aerocase is approx. 8 lbs. as you stated. The larger GA Aerocase weighs 9 lbs. But Taylor's statement on their website regarding the weight of the Aerocase being one third the weight of the Hard Case is absolutely NOT TRUE! Perhaps they originally meant to say the Aerocase was one-third LESS weight than their Hardshell Case. But even that would have been an exaggeration. The Aerocase is a really beautiful and rugged case, but it is also quite heavy. Taylor's website is misleading and should be corrected.
