Great report!
Similar thing happened to me last Sunday at Keith Wilson bridge.
Bunch of guys tossing roe and some were using wool including myself. I regularly changed the wool colour, but not even a nibble!
After 4hrs I'm still continuing with the same method expecting different results. A guys comes beside me tossing roe and not getting anything. 30 minutes later, he said I'm gonna change to something else. He put on a shinny spinner and I told him "let's see if this is gonna get you any fish!". Second cast, boom, Fish ON! I was laughing my head off and kicking myself in the butt. He lands a nice buck coho and I took a picture for him on his cell phone. He then starts casting it again and I told him "Let's see if it's gonna work the second time too!". Boom, fish on! But he lost it this time. Soon enough everyone starts tossing shinny stuff and since I didn't have any, he endogenously offered me one of his home made spinners. Of course all shaking and excited after 5hrs of fishing, I got it snagged in 5th cast. That was my cue to go home. I thanked him and wished him good luck while he was telling his friend on the phone about his success.
Overall a great day to be on the river and I enjoyed every minute of fishing!
