@Jernau,
A classic Sunray Shadow has an even longer wing and a hook placed in the absolute front. Some Sunrays are 20-25 centimeters or 4-5 inches long! Still the "short hook, long wing" flies have worked well for ages, and personally I think the fear of "tail nibbling" is vastly exaggerated. Most fish seem to attack with vigor, swallow most of almost any fly and even go for the front of the fly as they charge.
The Sunray Shadow can be seen here: http://globalflyfisher.com/patterns/sunray-shadow
And here's a whole article about short hooks and long wings: http://globalflyfisher.com/tie-better/short-hook-long-wing
The fly in the video barely qualifies as a long winged fly in my eyes, but is very much along the lines and proportions of most of the hair winged salmon flies fished here in Scandinavia.
