This guide is right on. I followed this guide today. Manny different mechs tried their luck against the "Funslinger" as I now call it. If a mech has an O'Sh17 face, I've seen it. Surprise is the key to this variant, for sure. It helps to tail about 500m behind a light mech. When the light takes fire and someone gives chase, they won't know you are right there to scrape them off. It's like fishing. Only, way more fun.
