Dada:
I've been using silicone flies for several years. The ones you posted under the pike patterns are what we along the Mid-Atlantic/Northeast coast of the U.S. call Siliclones.
You might find this useful. Tying instructions by the orignator of that fly pattern, Bob Popovics. Step by step instructions with pictures plus some background on it.

For your amusement here's a couple of patterns that I tie up in that style. These I use in fresh water for bass, pike, musky, pickerel and snakeheads. Two are tied on weedless hooks. I'm still learning how to use the digital camera so the quality of the pictures aren't that great.
