I love coated braids... I use them for 80% of my fishing situations. As already stated, they are tangle proof (if used correctly), abrasion resistant, have a certain anti-eject capability (if tied that way) and are probably among the most versatile hooklink materials you could use.
They allow: stiff-supple combi rigs, stiff rigs, hinged rigs, supple rigs, supple hairs, stiff hairs, etc, etc.
My favourites are: Kryston snake bite, Kryston mantis and suffix stealth skin although others are available. They all come with instructions...
