I have had the privilege to fish over huge numbers of coho when chums and humpies were also present. The conventional wisdom is strip for coho and pinks, dead drift for chums. I think that’s generally correct, but have hooked lots of coho on a dead drift and chums when striping. I think it’s a good idea to begin with the "proper" presentation than start changing up if that doesn’t work.

Try a wog if you see lots of rollers and have no takes on conventional methods. On occasion they love them.
