Scott, the guy formally known as FlatheadManic I think hes Karp now gave me a bunch of ear plugs a few years back. I use them from time to time still (although I've only got 3 full sized ones left) What I typically do is cut them in to very small peices about the size of a kernal of corn and then soak them in anise. It works, but I've never used them solo. I use the foam for the floating factor, not the bait factor its just an added benefit.
