Yeah, Skagit is awesome. It takes a while to get the knack of a sustained anchor cast. The entire concept is different than standard fly casting. In a normal cast, you back cast by accelerating to a stop and then come forward and accelerate to a stop (with or without a haul). With Skagit, the idea is to maintain a load in the rod the entire cast and then let the rod unload at the end.
Ed Ward is one of the pioneers of Skagit casting:

I went to a spey clave years ago an Ed Ward was there demonstrating the Skagit cast. All day, the demonstrators were using 15' rods with super long lines and would be casting 150' and expending huge effort to make the cast. Then Ed walks up with a cigarette in his mouth and uses a tiny 12'6" rod with a super short skagit line and sink tip to make 150' casts. His technique is super efficient and makes casting look simple.
