How clear is the water your fishing? Blue and chrome doesn't work try black and chrome if it's muddier or overcast, if its sunnier and clearer water go with the painted styles. Try 1/4 oz rattle traps or my favorite xcalibur xr25's, downsizing works tremendously.

I have seen days when they would bite a 1/2 oz better and the next day wouldn't touch it with a ten foot pole. One day they want blue/chrome the next day royal red, the next black/chrome. You definately have to experiment till you hit it.
