I just read this thread and thought it would be a good opportunity to make a comment.
We did an analysis of some of the "older" models back in early 2008, one thing became clear very quickly was the accuracy of Craig Crawley's Aardvark 767's - comparing them directly with Boeing's 3D drawings - they are amazingly good. I am hard pressed to think how the model can be improved upon other than perhaps a extra LOD or two, XML, or the need for Winglets...things I am prepared to live without based on these excellent models that are now SIX years old !!!
There is another point to make in that there is an updated paintkit for the 763 and 762 that make some pretty nice improvements to the original. Look for 763 releases from Maik and Garry over the last 18 months, they have been making excellent use of it. There are no 762 paints yet available but I am sure there will be soon :-)
Keep hold and keep faith in your old AIA 767 models - they are excellent and easily stand the test of time.
Cheers
