When Im out at shows, I usually bring my bag of patch cables, the ones that I used to bring when I was a patcher. Its weird when thepatcher doesnt have the right cables, and I have to supply them, kinda awkward, but fine.
Also with all the advances in gear, and patchers not following suit, makes for some uncompatible patches.
But, fwiw, my main worry is that I have all the gear I need, patchers are secondary. Most times, when I tape, there are no patchers.
