Just some food for thought for those guys guessing over 25lbs.  Banks Lake does not kick out those types of limits for two days during June events, though it seems as if it should.  Based on past WBC events, though folks do catch decent largemouth, this bite tends not to hold up and they are typically not any heavier than the typical smallmouth bag.  I do not want to discourage anglers from doing what they want to do, but it is important to consider past tournaments and the weights of the bags as you formulate your plan for success.
