Actually, I fish the "V" connection a long time, but then I got Davy's DVD and saw he does it too.
HERE, I can ONLY FISH 2 flies at a time by law, so that is as far as I go.
I found it interesting when Davy tied the tag on, that he took the end going the same direction as the main. I did the opposite thinking it put the other fly out there better. I never tangled much, but I could see what he was saying in that it could cause MORE tangles doing it the way I was.
I do use shorter rods on this but my 10' makes it effortless. I think it has to do with the size of water AND the fact I can ONLY use two flies.
Then in a magazine I saw these:
SO, I had to buy some. I love the fact that they can spin which means LESS tangles (again something that has never been an issue) AND the fact you can slide it up and down. I use those FROGS HAIR indicator stoppers.
I have fished this way for years, so it just seems so natural to me.
NO I don't think it needs a long rod.
