Ever had a dry fly that just refused to float like it should? How about a situation where the fish won't move up in the water column to eat your fly, and that fly just isn't getting down? These are the times that drive anglers insane (not necessarily a long drive for many of us, anyway). If only you had the right treatment to get your fly where it needs to be and keep it there. Dessicants, floatants, sinkants or added weight...
