With a state flood, i meant a syn flood for example. My experience has 
taught that small bandwith attacks (those that my uplink stands) are 
done based on my state table reaching its limits.

Knowing this, do you think I should have taken another approach?

Is there anyway I can assign conntrack resources per chain, this would 
greatly help at isolating damage.

The OUTPUT deny is a paranoid method to have a more complete 
understanding of that traffic and future applications cannot misbehave 
so easily. It is not meant to guard from ssh users.
