Gammarus Army

Gammarus flies, colours in "degradé" , ready for deployment

If we observ well, Gammarus species have a very flattened body and most of them have a hump on their back. 
I don't believe in ultrarealistic flies, but may be the shape, the "feeling" and  the colour of a fly is important.
An other important characteristic of the Gammarus flies is their weight. Deeper streams needs heavy flies.
Tungsten beads solve this problem, but what should be done, when a flattened body is needed?
A lead-based, multilayered body may be one solution, although several other techniques may be applied.

Wonder Wasp Fly

Wonder Wasp

The Hungarian Flyfishers Association (MÜHOSZ) use to organize on the end of the year a flyswap action. Quasi regularly.

This year a wasp-pattern should be tied.

The presented pattern was very effective for me this year for chub.

At the beginning I had problems with the floating ability. 

If an extended body is made of polycelon, the fly dives on its nose, takes are more ineffective, the fly swims, but not naturally.

Tied several variations to improve this pattern, here is the result:

Big Hole Demon

Big Hole Demon CDO Streamer (olive)

Once upon a time I found a streamer pattern on the web, called Big Hole Demon Silver. Tried several times for trout and it works. The frontal body is voluminous and pushes the water, the tail and the hackle prevents lateral deviation during retraction. The original fly has a body formed partially from silver tinsel. I considered, that there is a big lack between the tail and the body, therefore I renounced to the silver tinsel, despite the fact that it is shiny and attractive, but filling the bare section with something bushy (eventually cul d'oie) the fly is more balanced and produces more turbulence.

Follow my SBS proposal for tying a Big Hole Demon CDO streamer!

Pearl Streamer

Pearl Streamer (black and pink)

Smaller size marabou streamers collapse during retracting in the water, they are skinny and their real benefit is showed only when the fly is stopped during the towing, when they show an irresistible pulsation.

If we tye them with stouter body, with more feather, they will be more „muscular” during the towing, the water is pushed better, more traces are left, but at the time of stopping a pulsing tassel will be formed, which is not beneficial in all cases.
