Alot of people do need to depend on natural reproduction, me for example. My father and uncles (the land owners in my case) are not going to spend money on stocking 8" smb every other year, they would just assume go with LMB. Most amerature Pond bosses are not willing to invest that kind of money every year in a pond. But you are correct that put and take will gurantee you a smb fisery.
