The original, used to add fish-attracting colors from Wooly Buggers to large pike flies. Colors: Fluorescent Chartreuse, Silver, Gold, Red, Green, Royal Blue, Pearl, Pink, Peacock, Rootbeer, Fluorescent Orange.
Began using flash this year for kokanee and trout. Have never caught more fish. Love the pink and purple colors. Fun to mix and match different colors also. Can't believe how long it took me to begin using this stuff!! Will always have leaders in the boat tied up with flash!!
I tie a lot of streamer flies for walleye fishing. I like to add the Krystal flash to the bucktail. The Krystal flash seems to give a nice presentation in the water and keeps the fly up off the bottom.
