I finished my 7th symphony a few months ago using VSL Pro Edition. It's the last piece I am composing for that library as I just got the VI Symphonic Cube Extended edition and running it on a fast machine with 24 GB of RAM for new compositions/recordings. I am really impressed with both the quality of the samples and the user interface. The only thing that will take some getting used to is changing patches in Sonar, but I think I'll have it up to speed in a month or so.
These two movements from my 7th symphony utilize orchestral samples and software synthesis. I finished the entire work in May. Hope you enjoy listening!
