That pretty much summarizes the information I found. But I'm looking for how to rig the line. I know there is a line called "dapping tape" that acts as a sail, catching wind and sending the fly over the water. (By the way, I've also read that the stuff can be hard to come by in the U.S., and a good alternative is dental tape, unflavored.) Anyhow, I'm know there's a particular way to rig a dapping pol, and I've seen it explained generally. I just need to know what knots to use, how much dapping tape to use, etc.
