Dinsmoreoutdoors,
Wow, lots here, most everyone actually, knows more than I do about ponds. What comes to my mind though is: yes, most anything can be done if you work at it enough. A trophy bass may be different things to different to people. For instance, I would consider as trophy bass to be anything over 110%wr coming out of my pond, no matter the length. A trophy day might be to pull only 5 fish in, but all of them be over 100%. My ideas might be different than some other people's.
Would you prefer to catch fewer fish but for them to be exceptional specimens, or would you prefer to catch a lot of fish that were fat and healthy, but not necessarily 10lb fish?
If you want bigguns, there is some good info here on how to achieve that. And FL is a great place to do it too! Have you thought about trying to source female only lm?
