I agree 100% 767.  I didn't use it much before the Block F was introduced, but now I have been using this Captain Sims' 757-200 and now -300 constantly and I absolutely love it.  I also own the 767 your familiar with and it is a fine airline too, but something that I am really impressed with on Captain Sims is how user friendly the mouse controls are in the virtual cockpit.
I have not seen a virtual cockpit that is so easy to control as the way Captain Sim has made his.  The knobs and switches work almost as easy as if you were sitting in the cockpit using your fingers.  It makes it a real pleasure to fly.
I was having a little trouble figuring out how to set the heading on the MCP, but once I got it figured out (click with both left and right mouse buttons) it also is the most logical and easy way to work the "SEL" button.
On top of that there is so much function and visual clarity within the virtual cockpit I just look forward to "climbing in" every time.
I am very excited about being able to use this fine airliner and very grateful to Captain Sim for doing such a great job with it.  

Great screen shots 767.  I always enjoy looking at good screenshots and Captain Sims' flight deck looks fantastic.
