I put hem in the freezer. If there's enough salt they don't refreeze anyway. They keep for weeks that way. In fact I probably still have some from last fall in there!!!! I won't use them exept for bottom fishing, but the'd probably work. Heck those pesky springers bite a shiny peice of plastic with herring flavored petroleum jelly smeared on it!
Salt 'em, freeze 'em, if nothing else they make good "back up baits"!
(remember, you get what you pay for , MOST of the time!!!)
