In my experience on just about anything, HSL. The second somebody stops, bumps something, cuts a bad turn, anything that slows down the relative position of their CT to you, they just get ANNIHILATED. Big mechs get their backs opened up almost instantly, and anything not paying attention to you can be legged really quickly. I'm not 100% on doing it without some kind of poke weapon to back it up, but you're a pretty good flyswatter, so there's always that.
