I have a small pond (with SMB and BG) and IMO it is way easier to manage than a larger one would be. Small changes by adding to your predator base and/or removing a few by angling can make adjustments to the pond balance way easier than in a larger pond. In addition to what Yolksac said, if you think you have too much recruitment from your BG you can always add a few more SMB or WE or YP (yes they eat small BG) or .....
IMO starting with SMB and BG just means you might end up with a more diverse pond than originally planned...never know what you will catch when you toss in a line!
Bill D, what size is your pond again? I forget.
Do you have to consider carrying capacity when adding predators? How many BG per surface acre should be removed by angling per year? Does sex of the BG removed make a difference?
