Agreed, no problem running an unbalanced cable the length (or part of the length) of a mic stand. Where it can be an issue is if you want to run onstage but keep your recorder far off to the side, or run through the house snake, or clamp to a rafter DFC and run your cables to the wall, etc. One of my favorite spots to tape I can get in early to clamp my mics invisibly to the center balcony, but the manager likes to save the seats there for paying customers (specifically the ones who stand in line for hours to grab the best spot), so I run my cables far off to the side to leave them open.
Anyway, looking forward to the XLR Church mics.
