Run cut-plugged herring off the downrigger. Nothing between you and the fish but hooks and a swivel. Or you can use bannana weights. Troll or mooch. Darts and other jigs work well too for jigging. There is no reason to change what you are using. To save having to rebait, try trolling Coyote spoons instead of herring.

Flashers are really not needed, unless the fishing is extreamly tough (which is almost never) and it just hampers the fight and will harm wild fish that have to be released.

For some real fun, use a fly rod and toss streamers and poppers in the morning and evening. Or troll streamers or poppers to make a wake. Latter in the day, switch to a sinking line and use the same streamers.

Sekiu is very simple. The fish will bite anything. If you're not catching fish, then check to see if you have a hook!
