Not sure what this is

I'm still not sure what this is exactly.  But it does seem to be needing an integrated shelled hook,  using braided backing rather than mono.

....stemming from two questions.  How do you make a huge streamer still light enough to cast with a fly rod, and how do you make is super flexible to boot.

Huge streamers with lots of flexibility are cast with fly rods every day. A bigger wt fly rod is the answer but I’m curious to see where you go with this. Good work so far.

The first half of your question and your photo bring to mind Popovic's Hollow Fleye style, but like Mr, Deck, I'm curious to see where you're going with this.
