I have Just found two new Orchestral String Runs Demo's on Hendrik Schwarzer's OSR website, so I thought I would post the link here.
If you scroll down towards the bottom of the page you will find them there.
There is one called "Tangible Offering" using only the OSR strings by Frederick Russ, and another one by Rob Ellis called "Forged in the Fire".
I really enjoyed listening to both of these demo's! Thank you to Rob and Frederick for sharing these demo's with Hendrick to put on his website.
