Drainage mat behind stone veneer?

Question:
Is it preferred to have a drainage mat in the air space with a stone veneer (as I typically specify – EnkaDrain-standard) )
OR
Is it OK/ better to delete the mat and the air space (to minimize the opportunity to form condensation) and fill behind the veneer solid with mortar?
I would provide weeps at the bottom of the wall for water to escape in any case.
Thoughts?

Debra,
You want the drainage mat and the air space -- for sure. Adhered stone veneer installations are VERY problematic, especially over OSB.
