Chuck and Duck/Hatchet Cast

[Micropteris]

I am interested in all kinds of techniques of fishing whether it be fly or not. I am not about to preach or judge whether or not this is fly fishing or not, I really don't care if it is or isn't. I am just curious about the methods and why they are used.

I am intrigued as to why you use fly gear for this type of fishing?

Does the shooting line float like a floating flyline? I don't recall in the article it mentioning it. If so I could see using fly gear for mending and line placement for drifts and swings after the cast.

If the shooting line sinks and there are no reasons for mends and after cast line placement why not use noodle rods and fine lines for ultralight spin gear.
