Well Poppa, I've caught more than a few in Courtenay that were dime-bright. I don't keep the greenish-black ones.
Tastes are relative. I'm of eastern european hertiage so maybe I'm a minority but I served up Coho and Chum at the same BBQ and the family preferred the Chum.
The difference is that Chum hang out low in the river so mid-season, its hard to weed out the half-deads from the ones I want. Switching to Colorado spoon usually helps attract the fresher ones (and the odd Coho too).
Cheers,
Alex
