Dave, as you know Betty does a great thread furled leader. I however try to get my flies as deep as possible (smallies) so I have been making my own floro furled leaders and have been pleased with the results. However the other day there was little interest in my deep stuff so I went to a popper......and the floro furled leader made the popper ride too low in the water. I had a thread furled leader in my vest but went back to swinging big flies deep. Nymph fishing would be okay with a mono furled leader but dry fly fishing needs a thread leader. Hope you have more water in your rivers than we do in NE Iowa...fishing has been real slow the last 6-8 weeks. Jim
