Louis started the evening tying a Goran Sedge pattern with a Rabbit fur body, a wing consisting of 2 CDC feathers and a Mallard Breast Feather over wing. 
It was finished with a CDC hackle. An interesting pattern that looks very buggy and floatable.

His second fly was a Nymph that he called The Secret Nymph. One he was sworn to secrecy about many years ago.
This was tied with a Hot Orange thread that was also used as a rib and had a Gold Bead Head, Hairs Ear dubbing, a strip of Holographic Mylar over the back and then ribbed.
The fly was finished with a bright Orange collar tied with the Orange thread.
Great claims made for this fly.

Next was an unusual Spinner that incorporated fluorescent material.
Louis also talked about his methods of blending materials and threads adding a subtle touch of Fluorescence to the fly ( Flies ) A subject on its own…
The body of the spinner was tied with Fluorescent thread, Cock Hackle Tail and he used two Feather Tips for the wings, ending with a Hen Hackle at the head of the fly.

The final fly was a pattern called The Grayling Steel Blue.
A Palmered style fly, tied with Orange thread, a Silver and Orange Tag, Peacock Sword body and Palmered with a Blue Dun Hackle, tied in with a fine wire.

Louis also gave a talk and demo of his ideas for an unusual Leader and Tippet set up, with a profile starting with a fine or low breaking strain, gradually rising in breaking strain segments  to the middle of the leader, then going down again in breaking strain to the tip. Turn over is apparently amazing.
A guide to the set up and sizes below:
A neat trick was also demonstrated, to sink the first few inches of the tippet, with a small hook eye tied to a dropper about an inch long.
