Bought a fishing backpack from Cabela's today. It has good reviews and is on sale for a good price. I like how the setup includes an inner velcro divider where you can separate the inner backpack from tackle trays or if you want, you can remove some or all of the trays to create more space. The waist clasp also has zippered pockets to put more stuff.
