What Todd said.

Chartreuse egg sucking leech's and pink/white marablobs are good for chumlies.

Silvers and chums overlap on my home rivers pretty closely. As a result, I wind up fishing over chums and weeding through them to find silvers quite a bit. Chums aren't usually bait (cured eggs) eaters, but when the bait starts getting washed out and looks more like skeiny flesh than eggs, you can't keep chums off the hook. Kinda interesting.
