Since DLRO uses a Kelvin Bridge, the lead resistance is taken out of the equation, and you can test any length of bus by yourself.
I always recommend the end you put the banana plugs on the male plug side, since you then make a nice suicide cord that you could easily put a fused switch on to power up 120Vac equipment if needed.
I can buy 25' extension cords at harbor freight for less than $25 with the 4 clamps. Unless you like spending $200+ on the AEMC or Megger leads.
