Pat, I have exactly the same situation. My BCP are 12+in. and not many smaller and lots of LMB. We do harvest most all LMB less than 14 in. Maybe that's backwards and we should be harvesting the larger bass. I am not sure how well our BCP spawn but our LMB have no issues with that at all. I am considering adding some 8+ in. BCP this spring but that may be counter productive if I can't figure out the problem.
