Howdy, 'mower.
To get the most useful advice here, need to know more about your priorities for the ponds...I'm guessing from your post that a larger LMB population might be first on the list.
If so, number 1 priority is to improve the forage base. Feeding will help a little, removing as many LBM as you possibly can [ all you can catch below 12-14inches, and all that are skinny/bigheaded of any size] will help a lot. Unless you're really low on BG, adding fish probably won't help much and will be very expensive. Even a modest number of BG can produce hundreds of thousands of offspring, what you need to do is remove enough of the smaller predators to allow them to get to a size to be useful to your larger LMB.
As far as genetics go, even the best genes won't get you very far unless your fish have enough to eat.
