Bimini twist with an offshore swivel knot is my goto set up for trolling lines. But I still like a nice 4' plus loop for the doubled up line.
I use a similar method that utilizes the knob on a kitchen cabinet. I would record the process but I would have too much to bleep out as my wife would be yelling in the background, "you are going to rip the ^&%#$$& door off its $%##@!*& hinges".
