We also put a little bit of solder into the setscrew of the lug to add something to prevent it from loosening. Solder isn't really good at doing mechanical things, but its an improvement over just leaving it. All of this, of course, requires that you have a soldering iron capable of heating up the copper connector and 6 gauge wire.
An important point that you missed is "Strain Relief". That is, tie wrap your wires to a piece of the frame near the SLU70 so that part of the #6 wire will not move. This is the biggest problem with any mechanical connect, and it can be solved so easily. I'm trying to find a lug with strain relief to solve all of out problems.
