Here's what I do, and I'm 9 springers for 11 trips. When I plug cut that first big buck herring of the morning, from a batch I jigged at Westport and vacpacked, I wash my hands real good in the sperms - kills that predator scent which is what you want scents to do. After I've dragged the thing around for an hour or so I'll add some herring smelly jelly to the hooks and squirt some herring oil on the bait. But mostly I keep herring stink on my hands each time I handle the bait.
