I appreciate everyone sharing. In my specific case, the lake we fish, we can fish all day, changing lures and spots and never catch a fish. @riverratryan and I fished it yesterday for about 6 hours together, on the small end which is two large ponds connected to the main lake via channels, and he got 1 bass on a flat sided crankbait.
There was at well over a dozen other people fishing too. Some for bass, some for cats and carp, some bluegill or crappie. It has that much pressure every evening from about 3 until dark when the lake closes.
We watch what other people use. There is a lot of ned rigs, soft plastics, chatterbaits, and topwater. And of course a mishmash of typical bass gear.
I've never seen anyone using scent. If they are using it, its most likely something bought local. I am thinking something a bit more obscure or custom made might help.
