I don't think you have to give up on LMB/BG as the primary mix in your ponds.

With the options of HSB and SMB, you have some fish that do OK in cooler waters and coexist with LMB.

There are no absolutes when dealing with ponds. You may have a balance one year, or season, and that could change next year or next season.
