Re: Top Prop
Its been a while since I tied or fished any, but there's one tricky aspect of prop flies: you've got to give the prop a good surface to spin on. I've found that a thread mound often doesn't work, but a brass bead held in position with a thread mound helps.
Also, beware of their tendency to spin in flight and inadvertently make your leader a furled one.
All that aside, they REALLY catch fish. It just takes a little more attention to get the fly set up right and to cast it without creating problems.
