Littlezozo,
Procure is a good cure to use for steelhead by its self but it is a tempermental cure (sort of tough to use), and personally I don't like the color it produces. But Slam-olas main ingredient is sodium nitrate and that's an absolute no-no for steelhead, they hate it. Which is another reason why procure wizard doesn't work too well for steelhead either, it has the same active salmon bite stimulant in it. The problem with nitrates are, if the fish want them your on fire but if they're not in the mood for it you won't catch crap. We've played around quite a bit with nitrates and that's the only chem I've found where water temp actually affects how well they bite eggs with it, the warmer the water the more they like it. But personally I'll start with a base cure and add the bite stimulants the night before fishing, if necessary.
