The formula for growing big LMB is pretty simple, low densities of LMB along with high densities of appropriate sized forage.
If it were me with a small pond I would stick to LMB/BG and skew the initial stocking numbers so that I ended up with a lot of stunted 3" to 5" BG and low numbers of LMB. Your initial LMB stockers will have the best potential for growing to trophy size. In addition you would want to limit structure/cover so that YOY LMB fry were easily taken care of by the stunted BG and initial LMB stockers. You could add BCP to mix after a few years once the unbalanced fishery dynamics are in place.
Keep in mind that and unbalanced fishery approach will grow big LMB, but they will not be easy to catch.
