I would agree with their wisdom.
I have given up using bait for Coho for some time now.
Once I moved away from bait, my hook up and catch ratio seemed to go up.
I have found that in the right water, I will always choose flies and they will often out-fish gear.
I do use blades and do very well.
You have not mentioned it, but as I use flies, the closest gear item to the fly is a jig. I am not a jig fisher, but see the guys using jigs do quite well.
Sometimes it helps to think outside the box and not go with the status quo.
My buddy still talks about the day when we were fishing the Easter Seal run over 20 years ago.
Fishing seemed to be hot for a number of people, then slowed down. Nobody was catching anything.
On a whim, I picked out a rubber work from my Steelhead pips leader dispenser. I believe the guy beside me chuckled and thought I did not know what I was doing. In a sense, I guess he was kinda right, as I had never heard of using a rubber worm for Coho.
In the next 30 minutes or so, I proceeded to connect with a number of Coho, and landed 3. Rest of the pool was still slow.
Some items I grew up on using for Coho, but have not tried in quite a while were corkies and wool, Spin-n-glows, and the original BC orange Gooey bob. Still have some of these.
Have some other tips based on observations, but will let others provide their thoughts. One really clear and concise observation I have made, but do not want to give everything away.
