So to connect my fly line to my leader, I'm using the normal nail knot. Unfortunately from time to time my leader line will snag itself on the knot itself, and completely tangle itself up. If there anything I can do to prevent that from happening?
Are you trimming the tag lines off all the way down to where they won't slip through? Knot should be very neat.
Also, can you make a neat cast 9/10 times? Could be happening because you aren't making a slight motion away from your body while coming to 12 O'Clock during your back and front cast.
