in my experience , baby bass stay in close to banks and in and around cover . i wold cast it out parallel to the bank and twitch it around cover with a slow retrieve . also if you can get it out over the tops of grass by the banks would be good for big fish to ambush from below . what sink rate did you get ???
Like Soccplayer said, the point is to get the bait where baby bass are not supposed to venture.
This makes it appear confused, injured, vulnerable....all the things that make big bass lick their chops.
