A common use of "wobbler" type spoons such as the FST in salmon fisheries has been in river boat plunking situations. Much as suggested by Snake Pliskin they are fished off three way rigs though for plunking the leaders are usually a little shorter. Spoon sizes and leader lengths adjusted to have the spoon "wobbling" at just above fish eye level.

Local the smaller sizes are used quite abit on the Skagit during the pink runs and to a lesser degree for coho - especially popular there is the silver with red head color. The larger sizes are more commonly used in chinook fisheries such as the Columbia summer/fall runs. However in those fisheries the FSTs are being replaced by a new generation of wobbling spoons.

For salt water applications it seems like the narrow spoons - ala the coyote and coho killers -are more effective.
