Otherwise this is quick, dirty, cheap and works. I have used #5 at work, and am preparing to use it at home (S100 board with insulation displacement sockets from 3M, bought as a kit some time ago). These are *EXPENSIVE* (I'm cheap?) but I found them VERY easy and *QUICK* to set up and change, a valuable advantage for OOAK equipment designed for fooling around and cut-and-paste design. They can be damaged however if wires are pulled out of the bifurcated terminals towards the side instead of straight up. If this happens the terminals spread and the next wire into that terminal will not be gripped tightly enough. Also don't pull wires too tightly around corners on any method at they tend to short through insulation (very difficult to find!).
