OK, now I get it.
The AL wiring isn't bad as long as you occasionally (every 5 years or so) open up all your outlet and switch boxes and ensure your connections are tight (since they tend to come loose easier than copper). Also look for any signs of wires burning, etc. Maintenance is a bit higher on it, but it's not as dangerous as an FPE panel or Zinsco panel.
The combination of the two is a bit problematic, as a loose AL connection could cause the same type of problem I had in my home -- tremendous amounts of heat that translates into wires melting -- then you really want your breakers to be working.
