First, I am a pond neophyte, but love them. I'm same as you would rather catch SM than LM and enjoy catching big cats and eating them.
I think CC grow way faster than SMB and eat way more. Like has been said you already have a good CC pond just fish them there. It seems CC stir the bottom up more too making water look turbid.
SMB do great with YP and they might be a better substitute for the BG.
