My good old Albakore Lg. Bag has lockable trays with long bays . One holds 2 Cedar Plugs, 5-6 Trolling Feather Jigs . Have some Plano similar size boxes I can add or remove with smaller jigs and tackle that fit bag too. In winter I'd remove the trolling tray, add one with Heavy Jax/other rockfish jigs, weights.
Both have inserts to add or delete in each bay. FYI.
