A few more tips. Raspberry Jello added to your cure will do a few things. First the gelatin in it will add a little firmness to the eggs, secondly it will make the eggs a darker red, and the sugar is also an attractant (more so for salmon than steelhead). Orange, peach, and grape Jello colors also work.
If making egg sacks you can also add a couple of colored foam "puffballs" to the sack. They add a little flotation and also help stretch your egg supply.
When tieing your egg loop leaders wind about 18 turns of line around the hook on the front, end of leader through the eye and then 6 turns around the hook and pull tight. What this does is give you more room on the hook for your egg clusters and the added wraps spread the stress over more area of the cluster. What this all means is that you won't cut through the egg cluster nearly as fast in heavy water or if you bump bottom or swing and miss on a strike.
Bad eggs are better than no eggs. But good eggs are easy to cure and are far more productive.
Steelhead are more sight oriented so look is of most importance. Milder cures work well and are easier to work with. Salmon, on the other hand, are chemical junkies and a hot sulfite cure works better than milder cures. Will one cure work for every fish? Yup, just not as well as a cure tailored to specie. Most cure mfgs make multiple cures and for a lot of reasons other than color. Tidewater cures that milk heavily but are not durable. Upriver cures that are don't milk as well but last longer in faster water. Cures for upriver or for salmon that have been in the river a long time (more salt in the cure as salmon crave salt the longer they are away.
