Is a $40 adapter worth it or should we just re-pin the whole connector?

Last month I chased a bad ground on a King Air panel for 11 hours over three days, and it turned out to be a chafed wire hiding behind a clamp I'd already checked twice. I pulled half the radio stack before I found it, and by then I was questioning every shortcut I'd ever taken. That whole mess got me thinking about a real split in how we work: some of us swap a bad connector or plug in an adapter and move on, and some of us cut the old one off and re-pin the whole thing no matter how long it takes. The adapter crowd says it saves the plane a day in the hangar and the pins are usually fine, but the re-pin crowd says a crimp you didn't make yourself is a fault you'll never find at 2 a.m. on a ramp. I've seen a quick adapter fix bite a guy six weeks down the line when a pin backed out in flight, and I've also seen a full re-pin turn into a 6 hour job on a 12 pin plug that didn't need it. I'm honestly stuck on which side I land on. What's your cutoff, do you ever allow an adapter or a pigtail, or is it re-pin every time for you?
