I've fished for many years up in Washington and used various cures..The borax cure is good but i find that you need to have a lot of eggs cause its a real pain to keep them on you hook, also you need to be carefull with the amount of borax you put in your cure because it really draws the moisture away from the eggs.
Lately ive been using the chem cures and have had a lot of luck with Salmon and Steelhead. The trick is to get a good cure in the eggs and properly dry them...If the cure didn't take then when you put your eggs in the freezer the will freeze. I like to cut the skeins into 1/2" pieces before i lay them out to cure...
But then again its personal preferance FISH with what your comfortable and what catches fish for you.. I belive if there is i a steelhead in the path you your bait whatever it is Eggs, spinners, spoons, or flys, it will that it on the 1st or 3rd pass.
