Russ what is the size structure for your BG and LMB populations ? Adjust what you take out upon those numbers and your goal. For example if you want large BG then leave in the LMB needed to crop down the BG in the 2 to 4in size (6 to 12in LMB). If you want large LMB then leave in the fastest growing LMB and remove the smaller LMB (6 to 9in).
