For years Terry Hearn used black Amnesia as his boom on stiff hinge links, because it lay well, even though fluorocarbon was available.
I still use clear Amnesia in 15 and 20lb for mono hooklinks.
My braids and coated braids are from Kryston before they were sold by Dave Chilton. I bought plenty when I heard the sale was going through, so I have Merlin, Snakebite and Mantis in the 'original' colours (Merlin changed years ago from an olive green and white to a black white and green configuration).
Don't convince yourself you need your hooklinks to be totally camouflaged, nylon hooklinks are as good as any on the lakebed, only the abrasion resistance is suspect.
The Mantis Gold I use is a charcoal grey almost black colour, and Snakebite is green.
