GW the large lepomis concept has been widely discussed here. The tools and methods have been discussed. It is a fun question to ponder. Its the management level that is the hang-up. Most people don't want to do the management or incur the cost. The easiest answer for anyone wanting a pond to catch large lepomis is to create a put and take HBG pond with a limited predator. It works great but requires re-stocking and management. Feeding helps a lot in that situation. That type of fishery is IMO much easier to manage than the balance problems associated with GSF or BG and LMB. As Jeff paraphrased Bob - ponds are dynamic and always moving away from balance. That is the same in concept as my statement that - I have never seen or heard of a quality stock and forget pond.
