For many years while guiding spey fisherman, I failed to understand when and how to lighten up a spey rig. Milky inflated water can push steelhead into the shorelines and into some vulnerable holding lies! The problem is that many fisherman are too inexperienced or too timid to lighten up their rig and fish higher in the water column. If you are fishing too heavy, especially with longer sink tips - your swing doesn't finish and allow the fly to slide all the way into the shore. The tension dies too early and the fly begins to fall in the water column, becoming very unattractive to the fish. Steelhead don't suck up flies off the bottom! Suckers suck up flies off the bottom.
While you certainly need to keep your fly "in the zone", make sure your presentation is swinging all the way out to the shoreline. ALSO, consider that a fly is easier to see when silhouetted over the fish's head. It is much easier to see when overhead than underneath. There is a delicate balance here.
In cloudy water, I have really gravitated toward RIO MOW Tips. These aren't a "new" product. It's critical to know what they are and how to use them. The chief advantage is that you can extend your floating head, with a shorter section of sinking tip and this provides more control and steering for working the fly into the shore or around technical features.
