You haven't said the condition of the current BG? Walleye seem skinny and YP and doing good, but what about the BG? The reason why I bring this up is, will your walleye keep them under control. It will be interesting to see what Bill Cody would have to say about this. It seems like the walleye are going to prefer the YP first, then they will work on the BG if forced. You says the YP are in good shape, so it seems like the walleye are working on them as expected, but what about those BG?
Are SMB a possibility where you are?
