[Greenbuilding] voluminous wall cavities - limits to what one can reasonably dense pack with a cellulose blower?

I understand that it is possible with thick walls (10-1/4" in my case) to
find oneself unable to achieve a dense pack if the cavities are too
wide/one doesn't create enough baffles. In the case at hand I am in the
process of building a double wall (2x6 load-bearing interior, 2x4 ~Larssen
truss exterior) with about an inch and a quarter gap between the two walls.
The cavities are between 40 and 60 inches tall and 10-1/4" thick if as I
intend to I staple mesh across those narrow gaps. Is this adequate? Or
should I staple mesh *between *the interior and exterior wall assemblies
and figure out a way to blow cellulose into each separately? Comments and
suggestions very welcome.

Thanks very much.
