Shawn, LMB are double tough to control in a small pond. They can easily overpopulate and eat themselves out of house and home. Been there twice, done that, got the cap and a patch.
If you go for a 1/2 acre pond that you love to fish out of, consider about 250 bluegills, 50 redear and 200 channel cat. I'd go for one to 2 inch bluegills. The cats will get some but they'll also eat fatheads. Set up a feeder and be prepared to catch and eat catfish and bluegill. Toss in a couple of pounds of fatheads. When you catch enough of the cats, put some more in. You'll have a ball. Some hybrid bluegills are OK in a situation like this but they don't really get any bigger than regular bluegills. I don't see the benefit.
Or, if you really want to be a star, follow Cecils lead and ask for his thoughts on monster trout.
Remember the guy is selling fish. Read between the lines on that statement.
