I would agree with Greg. LCS is one more tool in the belt to be used in the proper situation. One would have to think about the situation and the tool options to decide. In the examples noted in the study there were + and -. I would not count on them to alone be the forage base for LMB. I could see using them in a pond (probably north) where the owner did not want BG because of possible stunting or in one without LMB as part of the plan. It just depends.
