I'll be experimenting with scent on some plastics this year.  Like most of us, I've used powerbait, gulp, and lots of other things over the years. Specifically, this summer I'll be using scented worms on a spinner rig - as opposed to regular worms from the bait shop. Might even be using a home made scent - soaking some regular plastic worms in a vegetable oil/anise/vanilla concoction in a ziplock.
