We don't really care about the bass...bluegill and crappie...
Your statement is a little ambiguous. People can only give you helpful advice if they know your exact goals. (Which can't be perfectly attained, but good management can get you close.)
Do you primarily want a bluegill and crappie pond? (If so, you still need a lot of bass to control two species that reproduce so prolifically.)
If you do want a BG/WCP pond, which is your priority:
1.) Trophy size
2.) Eating size
3.) Catchability
P.S. If your thread gets a lot of replies, people will switch to using acronyms. BG = bluegill, WCP = white crappie, LMB = largemouth bass
P.P.S. Some deep ponds out your way may also have smallmouth bass. Have you caught any SMB yet?
