Jakeroo, it's been my experience that if fed, HSB will prey on forage but will not put much of a dent into them. My FHM population which seems to be the most susceptible species to being extirpated from a pond due to predation has maintained itself even after the HSB were stocked. Now if they were not fed, there most likely would be different results.
Thanks for the knowledge here. I am hoping that I can repeat your results. I think my FHM population is pretty solid assuming they survived the winter. I also want to give the GSH and RES a year to spawn. If the lake is enjoyable with just RES/HSB, I will probably leave it like that. The more I read about BG and LMB on here, the more nervous I get about having them in our pond. I just don't think I can commit the time to managing the numbers that is required.
