If you want a Summer weighted Nymph that will take trout everywhere in New Zealand then this is it. Named Blue Death it lives up to the name. I use this behind a large Dry Fly on a 3/4 to 1 meter dropper and it slays!! The weight of the 2.7ml bead is more than enough to get through the water film. This means it reaches the view of the trout quickly but when combined with a large dry Fly will not sink, (the Dry). Once summer comes into force I will use this first thing in the morning until the trout are taking purely off the surface. You must have this in your Fly Box and you will want lots of them.
