I don't usually soak them in anything, but I got taken to school by a guy anchored next to me on the columbia this spring. He hooked 11 to our 2. He was using Pro cure's brine, possibly adulterated with some other secret sauce. I think the brine mattered, because we were marking fish after fish that went under us, and they weren't biting. We were using plain wraps, changed every hour or so. Sometimes I'll refresh them with Sardine oil or shrimp oil. Sometimes a little WD-40 as well.
