Yeah, I like the BOTH method. I was taught that the real purpose of solder was to exclude gas from the connection. Solder is a lousy (comparatively) conductor and is NOT a mechanical connection. Yeah NASA soldering means only enough solder to exclude gas. If you couldn?t count see the outer strands in a stranded wire, you were using FAR too much solder. I sure am glad I don?t make my living working to that exacting a standard. I must say though a roll of solder lasts me a long long time.

From my stint at a military contractor I learned that soldered connections are almost always more unreliable than a crimp since the solder turns a stranded wire into a solid wire and that breaks under bending and vibration. You could solder the crimped area if you went to NASA soldering school and maybe not put too much solder in the joint, but a crimped connection should be gas-tight and actually fuse the metal. That is why AMP crimpers cost 300 bucks. I am a sucker to buy them at the flea market.

When I worked on a U87 (in 1977), the center lead to the diaphragm was only a crimp connection. I worked on it because the crimp had become noisy. I am glad to see that they are soldering it now, though a soldered crimp connection probably would be better.
