Typically underperform? I suppose that might depend upon one's definition of "perform"?
I regularly catch HBG that weigh between 1.25 and 1.5 lbs, I never have to worry about them overpopulating the pond and stunting, (matter of fact, they help control my LMB yoy), and a HBG will hands down outfight a comparably sized BG (and I suspect a CNBG as well) anytime.
That's my kind of underperformance!
