If he's going to feed, a LMB/BG pond would require less management, and definitely a lot less money, long term than HSB because the latter would have to be replaced by yearly stockings, while the bluegill and bass will self-perpetuate once stocked and not require any supplemental stocking. Also, bluegill will be more dependable day in and day out in terms of catchability than HSB, significantly so for the average angler.
