I very rarely fish doubles because many of the rivers I fish in Washington State have single-barbless hook requirements in effect when I fish them. This makes it a pain to have a fly box with only doubles in it that I must then remember to take our of my fishing vest before fishing where the single=barbless restrictions are in place or run the possibility of a fine.
The doubles do ride very nicely in the water, and we must keep in mind that Kelson spoke of fishing small doubles in low water. Although he fished large singles in high water.
A G.P. tied in the original manner swims much nicer when tied on a double. but again, I rarely tie or carry them tied on doubles anymore.
