As you know from your own experience, when you have torqued your nut on the bolt and lock washer, the lock washer is effectively flat. The Navy's (and other's) observation is that the standard slightly spiral lock washer has about the same anti-loosening abilities of a flat washer, which the lock washer resembles in use.
Two nuts jammed on each other are pretty good in a high vibration environment, and if it works for you, go for it! The Nord-Lock is better, though.
All the best,

Huh? To me that's a non-sequitur. I don't follow.
It's still a spring, no matter if it's flat (while torqued). Thus it is not equivalent to a flat washer.
...though 40+ years of a anecdotal evidence could be wrong...
