I totally disagree with the advise you have been given. In East Texas, you can purchase 7" CC for $0.75 a piece. It would take an 8 lb. LMB to eat a 7' CC. In a lake with adequate forage (which I don't think you have), that 7 " CC could grow to 16" and over 2 lbs within a year. At that point, there is nothing in the lake that could eat it and stop it from eventually growing to 40 lbs.
