I'm making the switch over to plastics... been putting smelly jelly crawfish on my plastics, doesn't seem to hurt. Might attract more trout in - which is not a good thing if you are targeting perch.
Saw a suggestion from "Swift" I believe... krill oil scent. Forget the name but I've ordered some. I've thought about trying gulp juice...
What kind of scents to you put on your plastics? What is your favorite.
