Fly Line Leaders
Fly Line Leaders

YES!!!
Leaders for fly fishing are tapered from the butt to the tip. If you have a book that shows how to type fishing knots get it out and PRACTICE over and over again. The most used knots for fly fishing (after the one that attached the fly to the tippet) will be the blood knot and the surgeon knot.
Many flyfishers like to use a nail knot to attach the leader to the main line. There are machanical attachers that make it easy to change leaders if you want, They come in the leader package itself. I prefer to have about one foot of the butt end of an old leader tied to my main line with a nail knot then I attach the new leader to that with a blood knot.
Once you have it all together tie some pink yarn to the end of the leader and find a football field (or the like) and practice backcasting until you can do it without snapping the yarn like a bull whip. The hardest part is learning to WAIT until the line is layed out flat behind you head before you start the forward stroke.
Finding a video demo on YouTube will help shorten the learning cure. Like has been said before don't be afraid to take a couple of lessons. They will be well worth the money!!!
Good luck and let us know how it goes. We'll help you iron out the snags as you go along.
