When tying tube flies we are often faced with an ongoing problem. Feathers that would normally work well on a hooked pattern are often too small to accommodate the thickness of a tube. The most common example of this would be to think of a palmered schlappen feather. On a size 2/0 hook a standard feather would be fine, when you put it on a diameter of tube that is often 3 or 4 times as thick as a hook into the equation, that same schlappen feather now needs to be much bigger and longer. This is often the frustration that most beginner tube tyers face....."running out" of feather before the fly is finished! We have spent the last few years locating many sources of premium feathers more suitable for tubes.
