Sink tips work very well as a snagging device. All one needs to do is find a location where the fish are stacked up thick cast across, let the line drift down through the fish and hang on. This method is used quite effectively on salmon in the west. The 2 species this method seems to work best on are humpies and chums because of the sheer numbers of fish that will stack up in the pools. Sometimes you can find a dozen or more fly fishermen working a pool at the same time with this method. An amazing site.
