Walliceman,
Okay, so I'm not sayin' that they work for walleyes, but I have used them for trout. I like the 1/8 ounce size a little better than the 1/16, but both have worked when tipped with about 1 inch of nitecrawler for some dandy trout.
Around here I've only seen 'em in glow in the dark colors. I don't know if they make any other ones, but I prefer the blue or pink for the trout. The orange and green didn't seem to get as many hits. Don't ask me why though.
