Really interesting method, thanks for sharing. I have bunch of spoons but never been very successful with them. Most likely because not knowing how to cast and retrieve spoons properly but I will start using them with your trailing hook rigging method and try to gain more experiance. Perhaps a dumb question but would you think this method would also work or even help with blades?
The method would most likely not work with blades. The blades already use a small enough hook, and there (IMO) isn't really a binding point with blades anyway. These will work with spinners (blue fox and the like), however it does get annoying as the line will twist and bunch up at times. It seems to also drop the hook a bit too far back on spinners as well.
Pretty much the only reason I've done this is to combat the massively oversized fish killing hooks that generally come with spoons. It also allows you to change out hooks quickly, and you don't need to buy any specialized open eye hooks. As said in the article as well, all you need is a 100 yard spool of dacron (7 bucks), and a bunch of octopus or sickle hooks. With the hooks I use and the braid, I can rig 100 spoons up for ~$18.
