Lightly weighted rigs sink more slowly, giving bass a longer and better look. Twitch-twitch, sink. Twitch-twitch, sink. The whole retrieve process is more subtle and less violently active than is required when fishing heavier weights. To be sure, this rig won't penetrate thick weed mats, but most of the time I'm casting to the edges of things. Logs, stumps, rocks, weedlines.
