For years, I've always went to a few of my favorite spinners when the bite slows down on bait. I've always casted across the stream/river and then reeled the spinner back in from downstream to upstream as the current creates the spinning motion on the lure. Recently I've read about casting upstream and retrieving it downstream because the trout lay facing upstream waiting for food to come into their strike zone. However this seams difficult to keep the lure acting properly and suspended at the depth you desire, not to mention getting snagged up. So my question is... Do you cast UPSTREAM or ACROSS/DOWNSTREAM? Thoughts?
