Ideally you should have some 9"-12" bass to immediately start eating those 3" BG so they do not over populate in the next few years. If you don't have access to the larger LMB you can build or buy a clover leaf fish trap that will catch hundreds of those 2"-4" BG before winter. You don't want all those BG spawning next spring or you will have BG overpopulation. In spring before the spawn add the fingerling LMB or if you have fish small enough (1") for fingerling bass to eat then add small bass asap. You can add HSB with LMB and both will eat small BG but the LMB will be the best BG eaters.
