That is a perfectly reasonable question, which I have never stated aloud but I think I started off with just a dry fly without much success and then added the dropper after reading about it. I can say I have caught considerably more fish on a drowned black ant than any dry fly and possibly more than on a single nypmph pattern that I could name. I figure its like Kroger, they have watermelon, cataloupes, and honeydew melons. They probably sell more watermelons and could fill up all the tables with just watermelons, but they sell a lot of the others because they are there.
