Totally agree; on the bobber/fly with spinning rod set up! It's worked on the Deshutes, for me, below Lava Lake. It has also hammered literally hundreds, of 'bows, in lakes over the past 5 decades.
The main differences--between my rig versus the video--is I use about 4', of leader. And I use Improved Clinch knots, at every connection point. Plus I use, a Torpedo Bobber (see pic). Then I crimp on a small BB sized split shot--about 1' above a Woolly Bugger, or Teeny Nymph. The weight drops the fly, so it is just "sub surface".
Such a set up, would work well for "nymphing" in a stream. Or remove the split shot, for fishing any type of dry fly on the surface. Black and Olive Green, have been my "go to" colors in lakes..for sub surface fishing. Dries that imitate terrestrials (ants, grasshoppers, spiders, crickets); should prove most effective in streams this time of the year.
