9 Fish Down and Across, Please Whether you're working a streamer or a light spinner, it pays to make your presentation across prime holding spots in a broadside manner rather than coming head or tail downriver first. Cast across and slightly upstream, then begin the retrieve. Let the current swing the streamer or spinner so it crosses in profile across the lie. With the fly, you'll need to flip (mend) any line belly upstream, then give a moment of slack before beginning to strip again. When using spinners, try opening your spinning reel bail to spill line, giving slack so the lure wobbles downstream to the next trout lie. Just as it approaches the sweet spot, close the bail and tighten up; the bladed bait will swim in front of the trout.
