  The weight of the most line the rod can aerialize typically is another 30 feet or so (60 feet of line in the air), or about 20-25 grains more. When sizing a shooting head for a rod, choose a weight of the head equal to the weight of line that properly loads the rod with as much normal fly line as can be aerialized.
