Making my PSU cables literally 20 times better (0.6 to 0.03ohms)

My old bench PSU cables had a resistance of about 0.6 ohms between the cable resistance and the original banana plugs. That might not sound much, but at high current and low voltage it makes a difference, and that's especially obvious when testing LED torches or flashlights with the PSU in place of the battery to get an indication of current.

I decided to make a set of new cables with better connectors and cable, but couldn't decide between 1mm vs 2.5mm CSA (roughly 17 to 13 AWG). In the end the decision was made by the discovery that the silicone rubber 2.5mm cable wasn't what it seemed!

With the new banana plugs and cable the resistance of the leads and connections has dropped to 0.03 ohms, which is much more acceptable.
