Fly Pattern Identification

I just saw a pattern that is being used to catch salmon and I did not quiet catch the name. It was some like "Estis Fly" of simular. The name is probably spelling wrong but the pattern is made using Glo Bug material tied onto the hook and wrapped forward. Then the back is clipped even with the curve of the hook causing it to flare slightly. The next step is to wrap chennille from the front of the hook back to the flare and forward again. This is not regular chennille but is (large or medium) ice sparkle????. Give it a sparkley look. Then whip finish the head and cement.

Any idea what it is and any pictures of "How too".

Estaz! That must have been what it was called. Now did anyone every see this tied as mentioned above?

Hey coach look at this

ny angler, thanks for the reply. It is getting me into the right ball park. The tail on the one I saw was glo bug material (flared out) and the body was Estaz wraped aroung to the front. I tied up what I thought I saw and it came out fine. Let you know this weekend as I head up to your state after some salmon.
