Scientifically... I cannot say, however several patterns I have tied with UV dubs have been good producers and have shifted into my most carried fly boxes. Not really having compared identical patterns with and without UV on the same days in the same water, I cannot say for sure. It may be more of a confidence thing. One tends to fish with what he believes will produce best, therefore when he does catch something it is immediately attributed to the fly chosen.

All that gibberish aside, I like it.
