After a 7 or 8 year hiatus from trout fishing and tying trout flies I began to re stock my depleted trout fly boxes. During that time I mostly fished saltwater and tied only saltwater flies. I've not kept up with the new flies, materials, patterns etc. for trout flies. What are the best fly floatants available now? I want something that won't change the color of the fly and something that I can pre-treat the flies at the tying bench. Any suggestions?
