Use your fly or spey/switch rod.
Farther out you can bomb the better and if you've been casting that long now you should easily be able to get out to them.
Try California neils in green and teal. Sand lance patterns and other baitfish patters (mickey finns, rolled muddlers, etc) will also work.
As for spoon fishing, that is best when the coho are way off beach and you need to really BOMB it.
I use a 9 ft shimano rod rated 1/8-3/8, 4-10 pnd test. It's perfect for them in rivers and off the beach. Can put spoons a football field off shore with that rod.
Off beaches you can't beat the gold hammered croc with the orange fire stripe in 3/8. If that ain't working try a blue fox spinner size 4 in blue or orange.
Rivers... Koho (orange/illusion), Little cleos (silver and silver/orange), kwobbler (silver) and of course crocs are your best bet. Kitmats also rock in illusion.
