1/0 lugs with hydraulic crimper
Using the #70 hex dies in my new hydraulic crimper with 1/0 tinned copper lugs (not cast) and 1/0 cable. I squirt a little anti-oxidant around the lug hole, insert the cable and do a simple crimp. ...

It would be interesting to see what sort of crimp was used for the testing in Trojans white paper. I've seen an awful lot of data/testing showing just the opposite over the years. In the aviation industry we use solder type connections quite often for low current applications, and in fact have to re-certify on soldering on a regular basis to include having your joints checked under a microscope. High current connections however are always crimped. A lot of engineering work goes into determining what sort of connectors to use for different types of circuits, and these are continually being re-addressed based on MTBF data and incidents investigations following failures.
That said, a proper crimp results in cold welding and a gas tight connection that will result in a quality low resistance bond. Most of the shade tree mechanic stuff I see involves a crimp with pliers, or one of those hammer type crimpers resulting in questionable bonds. Resistance, corrosion, and eventual failure are pretty much to be expected in a crimp improperly done.
