Well, if they work as well as your chum jigs, hell yeah! I'd be very happy to purchase some if you do that sort of thing...
Hahaha actually they are so simple as most are just a wing of flash and some tinsel body.
Tell me when you are going and I will try to go too, I'll give you some at no charge bud! epoxy patterns to little sand fleas and random stuff. Best thing I can tell you is that the speed of your retrieve can play a big difference in how some fish will take, slow at times or fast/ two handed stripping, or even random stuff can get those coho to hit.
Used the spinning rod, nothing except for the tiiinest little smolt who tried to grab a Gibbs koho spoon 3/8 which was almost as long as it was.

Saw two other fish landed but it was sooooooooo slow, only one jumper but it was WAY out there.... warm weather keeps them far out it seems.
Please pinch your barbs even on trebles, not sure what happened but I don't want to make assumptions right now about the father with his kid who lost a orange vibrax size 1, dink float, two pieces of hollow lead and 30 yards of line. I pulled in all that stuff your son lost and you didn't pinch the barbs on the treble but please remember to pinch your barbs.
