Eh, sane is a stretch for any of us at 12 percent battery. You were probably running on two hours of sleep and half a brain cell like the rest of us.

I've noticed this same thing with a lot of "pro" tools in general, people push the expensive option like it's magic and then you find out it only works right if every single thing lines up perfect. Quad shield is thicker and the cheap dies on a lot of crimpers just don't bite right, so it slips, and you blame yourself when really the tool is the problem. It's like buying a fancy knife sharpener that only works on one brand of knife, that's not you doing it wrong, that's the thing being too picky. Twist-ons get knocked for signal loss but in a real apartment building with short runs the difference is tiny and you save your hands and your time. Sometimes the "correct" way is just the way that actually gets the job done before lunch.
