Has anyone used the Miroslav Choir Refill for Reason? Pros and cons? How does it compare to the choirs in EWQLSO Silver? Is the Miroslav refill suitable for more quiet passages as well as that big bombastic sound?

It sounds pretty okay to me but I haven't heard of anyone using it yet.

Is it better to load up Reason through Rewire for choirs or to load up another instance of Kompakt for the Silver choirs? Which would be easier on the computer?
