Okay I have an idea...
Imagine a test lead organizer that has a slot for EACH END of the cable, and a spring loaded mechanism which pulls the cable tight (gently)
Now limit it to one test lead per slot, and make it so each spring loaded slot acts independently so it can auto adjust to various lead lengths.
Its kind of like a guitar, with test leads as the strings, under much less tension, at different lengths, and with very easy removal and installation.
The thing is, you don't want to have to mount the top slot 5 feet up and have this spring loaded slot down near the ground..thats very cumbersome
So maybe you pack things so this contraption floats all at 5 feet somehow and forms a U or something
Damn I think that will work
See attached pic.
So one side has a "combo" where all the slots are fixed in position, like the pomona.
Then you have a pivot of some kind a couple feet away that you wrap the test lead around..on its way to:
A set of spring loaded MOVABLE slots (one per test lead), that pull the test lead taut (gently)
You can repackage this and be clever to make it cheap and simple and take up the least amount of space.
But I think it solves alot of problems:
-1 test lead per slot means no confusion, you can instantly see both ends and know what each is
-Since its 1 test lead per slot, its not in "series" anymore..you only have to remove the one you want
-Spring loaded taut means no more tangled cables or snags, nothing falling out
-Spring loaded and taut means it looks much nicer than a wall monster rats nest. Still looks like an engineering item which is fine
-Loading and unloading fast and one-handed. Snag head, pull around slotted pivot (has guides too), lock head into spring loaded hook, release hand, satisfying twang as lead pulled taut (gently)
EDIT: I think you could rolls this into a tube so each hook/pivot/hook set is on the cicumference and you can spin the tube to get the one you want..takes up less space possibly so you can mount it under a shelf on your workstation, or vertically on a wall
