Nice article enjoyed the read. Now that we are on the topic of kokanee fishing I thought I would bring up a speculative kokanee rig... I have often wondered if running a 0000 or 000 dodger with a bare hook setup would work for these guys.... probably a size 6 or 4 harness with just a bead above it or run bare. Works for sockeye, why not kokanee? Never tried it but have always wondered.
Also, I find the standard double hook worm harness rig can sometimes lack the holding power to land kokanee due to the fact that their mouths are extremely soft. Over the years I have adapted a modified treble hook to most of my wedding ring spinners and have found they help out quite a bit. I like to wrap my hooks in chenille with a bit of flashabou or tinsel. The tinsel ads flash, and the chenille works great to hold scents applied to the hook.
Another thing to consider when fishing for these soft mouthed fish is the use of a trolling snubber to dampen the impact of the strike and keep from ripping their lips! I use snubbers when available, but do well without.
