disclaimer; I'm not an expert.
I would include some LMB or HSB if you want to catch some decent size BG. If you don't have either LMB or HSB you will eventualy have stunted BG.
I would go with LMB but that's because I love fishing for them and they make good table fare. If your not into fishing for and eating LMB then you could go with the HSB since they will not reproduce and will be a little less maintenence. Just my .02 cents.
The experts will have to help you with stocking ratios.
