Gator ,
Sounds to me like you have an awesome place!! Congrats.
I am by no means an expert in the pond management category.(Come to think of, Any category) But I too have a similar situation going on. 10ac. BOW with LMB,BCP and BG. I have owned it 7 years now. I put the BCP in before I knew they "Might" become a hard to manage resident. As of right now I experience much the same results as you. In my mind the lack of cover and sometimes 8+ feet of visibility let the Bass keep the Crappie in check.
So at this time I just keep enjoying the great fishing. Hoping I don't have my head in the sand. Although I do have future plans for a small grow out pond for Red Ear and then maybe Bluegill. My Back-up plan are the Hyb-Strippers. Good Luck!!
