Gregorian Chant / Monk Choir Sounding Stuff?

[Deadlove]

Could anyone recommend something sound module wise that has a relativively convincing version of monks chanting or similar?

Rite now I'm working with Symphonic Orchestra Silver and it has some cool choir sounds with oohs an ahhs but it doesn't sound like church / religious really at all.

Thanks!

Reason actually has a really good sounding monk suite. There is one for Kontakt 2 but I can not remember the brand, a lot of the samples are the same.
