You have a very difficult lofty goal that is very rarely accomplished if you want a 10 lb LMB. The general consensus here is to avoid GA GiantBG. They will definately not help grow bass.
I think you will have a better chance growing more 8-10 pound predators in a 0.75 ac pond if you use HSB compared to LMB. Even with good culling of small bass it will be quite difficult to grow just one 10lb LMbass in your pond. There is hardly enough habitat and growing area available in 1 acre to grow several 8-10 lb LMB. Carrying capacity plays a big role for limiting production of big fish in a small pond. You will have a decent chance to grow several 4 to 6 lb bass. Growing them to 8 lbs becomes more difficult. Then catching the largest LMB will be very difficult after they have seen numerous year's worth of various lures used to remove/cull small bass. Each time you catch the original stocker bass they get more hook avoidance smart.
To grow a few big LMbass in your fairly small pond, lots of important factors will have to come together. Factors like proper culling/harvest, constant high amounts of diverse forage types(not just BG), low angler hours, great genetics, and lots of luck. In your process of significant bass harvest you will be teaching the oldest bass to be very hook smart and to avoid lures. If you can't catch the 8lb bass does it really meet your goal?
Other forage items to consider for growing big bass would be threadfin shad, crayfish, tilapia, and very likely trout added each late fall-winter, early spring after the LMB get to 5 lbs. You will likely have to spend significant money each year to add stock amounts of large sized forage.
IMO I would not use papershell crayfish for growing big bass. Papershell do not grow to a big enough meal for bass over 4-5 lbs. A better crayfish would be white river crayfish (White River crawfish) or red swamp crayfish (Procambarus (Scapulicambarus) clarkii.
HSB will feed heavily on pellets and grow fast. They will have no reproduction so you will not have to remove lots of young bass to keep the natural foods abundant. Pellets will keep the predators growing. Not fishing for small bass and just fishing mostly with smallish lures for panfish helps minimize hook smart large fish. More HSB can be grown to larger sizes in a small pond compared to LMB unless you use ONLY pellet trained, female excellent genetics LMbass which are extremely difficult to source.
Look though the archive thread about growing & managing LMB for posts discussing growing big bass. Compare the information to information about growing HSB.
