As Josh Knows, I am a firm believer in large planks, stumps, Big poles, big tree limbs, other BIG stuff, etc., for BIG Crappie cover. Smaller brush and diameter cover works well for smaller fish, and dense cover is needed for baitfish, fry, and the basic food chain. It is an easy system to follow...you just have to be willing like Josh to put in the time and work!
What Josh has done, is the plan and blueprint that others should follow....I will not argue about which cover is best, because Josh's results speak for themselves....he sure has Done his Lake up right!
