I fish a ton in grass and weed beds. I agree with the earlier posts, weightless senko or dinger etc. I will work it two ways and usually they like one or the other any giver day. i will slow drag it across the top, as close to parralel as I can cast. I have also been killing them by jerking it through the weeds as if it was a fluke. Leave some slack in the line and snap snap a couple short times. They pick it up on the fall almost every time.
