Sometimes, when I'm tuckered out from chasing a dozen or two kings halfway to Timbuktu, I try to trick them into going upstream right when I first hook them. I give them just enough slack so I can run like hell downstream just far enough to get below them. I still end up chasing 90% them downstream, but usually not as far. I also get a higher % landed this way too if they don't get off before I tighten up- the hook tends to set better,and I spend less time fighting them from below me.
