here's my 2 cents:

Steelhead: stick with skein eggs, and I recommend a plain and simple borax cure .

Coho: Skein eggs cured with many off the shelf cures (in red), pretty much any of them will work as long as it is red - or they won't work that is just a coho fishes prerogative...

Chinook: Here is where roe sacks can be of some use. I've found that Chinook are the pickiest about the bait you present and when I've had the time the day before I fished and had loose eggs to use... I would make up 6 or more variations of roe sacks, for example: eggs and prawn, eggs and tuna, eggs and herring, then some with various added liquid scents. you get the idea. oh and also, they are a good place to put the heads you tear off a sandshrimp... if you're into that sort of thing.
