Re: Feather Craft Furled Leaders
I think some of the previous posters correctly nailed the leader spray problem to braided leaders. The construction process used to make a braided leader results in a hollow space inside the leader. Picture the braided looped connectors that you can attach to the end of your fly line. This hollow space created in the braided leader can partially fill and carry water which in turn causes the spray.
Furled leaders are twisted, like a rope, so there is no hollow space. I imagine they could be made using a material that absorbs water, but that that usually isn't the case.
