With such a deep, quick drop and a lot of pads lining the shoreline, that may be part of the issue... not enough good BG spawning area. It doesn't take a lot of space, but you may want to look into clearing some shallows (out to about 4' deep) a bit so the BG have good bedding area with ample sunlight. It will only help the entire food chain. 200 3-5" BG will definitely increase your recruitment if they have a place to make babies. They are a bit more expensive if you plan to purchase, tho.

Keep in mind, a LMB will target forage up to 1/3 it's own length. So if you have several 16"+ LMB, a lot of those stockers will become food at a rate of 3-4/day/bass. It all depends on your goals for the pond as to how to manage your predator base.
