I most likely carry the smallest assortment of flies of any flyfisherman on this forum. I have four basic sowbugs, one mayfly nymph, one egg pattern, and one barbell zonker. I carry 6 zonkers in the same color and 18 each of the sowbug, mayfly, and egg pattern. Over the years I have narrowed it down to these 7 flies to be my most productive, day in and day out, including night time. Trout eat the same things at night as they do in the daytime. The menu does not change.
