I really believe that if you use the CO/ALr devices and the Kings or Ideal 65s for splices you would never have a problem. I still think 99% of the "aluminum" problem was workmanship. The builders who cut corners on materials were also cutting corners on labor and then you had homeowners in there "improving" their house with whatever they found at the hardware store. I wonder how many of these problems were in things Harry Homeowner or the handy man "fixed".
One thing that is evident is if that house was going to burn down, it probably already has. There are millions of homes that never had a problem.
