Q: "I have fished a lot in big lakes and streams, but now I would like to try saltwater fly-fishing, especially in Florida. I have a good saltwater reel, but I don’t know if it should be loaded with gelspun braided or Dacron backing. What do you suggest?"
A: Unless you will be fishing offshore, I suggest using 30-pound Dacron line for backing. I have reels loaded with 30-pound Dacron that have been in continuous use for a long time and have never failed. I don’t recommend 20-pound Dacron. My experience is that it doesn’t wear as well when fish pull it through the guides during a fight.
