Standard dry fly wire
Modern drag systems are designed to give you leverage over the fish
There are a lot of times when the fish will just come up and barely get it, and if you have a big bow in the line youll miss it
For instance why does a dry fly hackle when wound on an uneven surface (i.e., twisted thread, bulky surface, etc.) lead to a fly with the barbs strewn all about
The Winch JX 6/3S shines whenever fish need to be muscled out of deep water, heavy current, or structure
While the two lures may have been competing for eyeballs and sales, in terms of ease-of-use, design, and fish catching ability, I always felt the Flying Lure had the Banjo licked
