2. I've saw some you tube clips from Pacific Northwest steelheaders who use slinkies on the weight to avoid startling the fish by damping the sound of the weight bouncing on the bottom. Basically the lead is covered with heat shrinking pcv or I guess surgical tube would work as well.
I think I saw the same video, it's by a "steelhead stalkers" or something and they're out of Washington. I think it's called "drift fishing".
His favorite way to rig up was to use a slinky (you can buy them at Sea Run), or make them using paracord (3Vets etc) and buckshot. Cut paracord into desired length, fill with buckshot or split shot, use lighter to seal paracord end (s).
He would poke a snap swivel through the slinky and put the eye through the mainline so it was free floating, then tie on a swivel, to a 2 ft leader.
I believe Milo is correct on the technique and all he says about it (I've never done it). If you go to their website (guys who made video), you'll see he writes about short floating like he recently discovered it and it's better than sliced bread ..."I wish we would have done this when we started".. because the learning curve is way steeper. He seems pretty legit to me.
Snagging bottom all the time would be a bitch. Logic would have it that drift fishing would be a lot harder, but give it a shot, I've lost enough pencil lead in the river so I'm not going to throw stones. I also love the sight of the float diving. I think that's the best part.
