Coho, and other salmon species, are well known for having short strikes. One thing you can do to compensate for this is to have a trailing hook.
Rather than tying that second hook so it ends about where the hoochie ends, you add a couple of inches.
That way when a fish goes for the hoochie, if they miss they still have a chance of getting that trailing hook.
You can put the hook so it starts at the end of the hoochie (as pictured below), or even drop it back a couple of inches.
