Galloups streamers

I don't know about Steelhead but Steelbows will take them. Kind of a high time / cost fly to choose. Personally I feel there are better Muddler variants to utilize on Steel. Kelly's signature is largish spun and clipped deer hair heads.. not the best for sinking a fly to be swam quite slow in COLD water. With warmer water temps and some soft even strips thrown in the mix they could be a viable choice. That large head and Mallard flank flat-wing give them unique action on the strip, but also inhibit sinking.

A lot of us here in Northern Michigan fish Sculpin ties.. mostly Woolhead or Aussie Possum. This material soaks up water and becomes neutral rather than buoyant like hair.. yet still has the bulk required to move water, tickle that lateral line, and create the correct profile.

Look into Kevin Feenstra's ties. One of the pioneers of success on swung fly presentations in my local.

Tube variant of Kevin's "Aquatic Nuisance" tie.. spun by my long time friend Forrest.. owner of Heritage Angling Products (HAP) Kevin's original is subtly different with rabbit zonker wing.

Cold; I was stumped as well when I first saw this head in 2002 on Kevin's "Emulator" (a variant of this is personal staple I call Emulation) It's really so simple it eludes the brain. After working with wool so long I was all caught up in how to achieve such a perfect integrated collar. This is the Aussie Possum. You pinch and shape desired size bunch then clip tight to the pelt skin. Shove it over the hook eye, shank or tube and lash down tight. The forward head is actually clipped into shape, much like deer hair, collar is the un-clipped guard hairs. It's a great material.. popularized by Kevin.

Another guide on same river (the Muskeegon) coined the acronym "MWM" ..motion without movement. Quite often we are fishing waters less than 40* F - You need to capitalize on flowing sparse materials that provide a full profile illusion of life all on their own. Need to achieve that deep sunk slow / even swing that's majic.. like a gold watch pendulum before their eyes. Stripping, as a rule, is harmful until warmer water is the norm.
