Do you use them with success when grass isn't present at all?
I fish them quite a bit. I like to use the lightest weight possible (1/4 or 3/8) except in stump fields. I like white, white/blue, white/red and white/chart. I use a knockoff of the Zoom swim chunk as a trailer. One thing I learned is to not set the hook when I feel a fish take hold. I just keep reeling and let the fish hook itself.In stump fields I use a 1 oz jig and let it bounce off stumps as I swim it back. I have found that lighter weights don't get me the strikes in the stumps that the heavier ones do.
