The colors are awesome and subtle amount of flash makes it even better!! I use this dub for over wings of smaller baitfish patterns and bellies of lager flies. It has good length to it for carding as well. The dyes used for the hot colors really glow under UV light, especially the purple. It's really hard to find a purple color in any product that reacts to UV light... When I am fishing for striped bass at night, you can bet I will be using a black and purple fly, with a belly of purple Senyo's laser dub, off the chain deadly!!
