It sounds to me rbuck that you would like to catch larger LMB. If this is the case get rid of quite a few small bass and as many crappie as you can. I have had the same problem in my father-in-laws pond from an unwated visitor dumping a couple of five gallon buckets of crappie in. This screws up your food chain in small ponds. Like the others said, I would suggest starting up the fryer for the crappie and adding some bluegill in the mix.

Anyone in need of a fisheries biologist to put to work???
