hey
yeah I do the same, I try and keep all my main speaker cables wired normally (so they can be used for all jobs not just certain ones) and have some short 50cm or so pin swaps, bridging adapters and spiders to split/change/adapt things if needed.
I heatshrink some labels onto them to mark what's what same as chris, and also use different coloured speakon bodies on these for quick recognition when they're in a box/case with other cables and i'm digging through; red for Bridging, green for pin swap, yellow for only two pins wired and normal grey for standard 4 or pins wired as normal (for NL4 and NL8 respectively).
