Think about this. At your pond size changes in direction are not real hard. Start with a balanced approach. You can feed the BG a little and that will help. But shoot for balance to start. If after you try that a while (year 3 or so ) you can change directions by fishing , seining and or traps. You could go either way - trophy LMB or trophy BG or stay balanced. If you like fast action and large BG you might go to trophy BG by letting the LMB overpopulate. In the mean time you can read here about what both offer. Either way you would start with FHs.
