I don't think the HSB will be a good predator of the LMB. HSB stick to more open water, where LMB stay relatively close to shore/cover. I still think angling is the way to go.
Scott, I know that you know this, but just for clarification -
the only way for HSB to control LMB recruitment is with no or limited cover or structure.
HSB as well as striped bass, being only an open water species is a myth - fish will follow the food.
