Triploid, Humpy & Seaplane Hater
There just isn't a lot of gap on a size 6 octopus to bury the hook. Since aggressively feeding coho aren't leader or hook shy, you might give that a try. Especially now that we are getting into prime toad time. Personally I've lost to many fish on small hooks so I mainly use size 2's and 1's stingers now.
Good luck out there.
