I do the same bucktail (white with mylar) treatment on my saltwater hooks, and I think it is effective. The bucktail also holds scent well. The paste scents (e.g., Smelly Jelly) last longer, but they tend to mat the bucktail so there is less fluttering than one would want. The liquid scents do not last as long, but they do not mat the bucktail. Mike's Herring is a good liquid scent in the salt. (My son also does well with Mike's Herring in freshwater, which I find surprising because herring are not found there.)
