apt - preferences

--------------------------------
I was hoping to get:
always follow stable but allow specific calls for 
testing/unstable.  (which would be like: 700/50/50)

But, if it's 'testing' keep following the version for testing 
allowing upgrades as provided.  This is where I got stuck.

With the above, when I do:
apt-get upgrade
then everything upgrades stable->testing
which I don't want.
I do want to be able to upgrade manually (apt-get -target) to 
different archives, but can I keep those package following that 
archive without editing the preferences file?

So if I do 'apt-get --target testing mozilla', how can I keep 
following the testing/mozilla package?
