The temperature factor is a good point, Wade. I wonder which is more important in a scent product, the scent trail to attract the fish or the taste of the product that gets them to hold hold a bit longer, giving the angler a second or so more time to set the hook. Because both factors are obviously important I may try to use, at the same time, on different parts of the lure an oily scent to create the scent trail and a sticky scent for the taste. To some this may seem to be going too far. I have used combinations of scents before. When mooching for salmon I sometimes inject the sardine or herring with an oily scent, then coat that bait with a sticky product. ( I also heavily coat the exposed hook with a sticky scent when mooching for salmon.)
