I believe big GTs are territirial and with it's mate , guard a particular corner of an area which is the prime ambush point for them to attack the passing fish .
Big chugger which landed in their territory and worked rigorously like an attacking fish is treated more as competitor and to be driven away , I have seen my chugger being head butted clear out of the water without the fish wanting to eat it but time to time , when doing so , the fish may got snagged by the trebles .
Unlike stickbait which resembles more like baitfish in action and hence will be eaten rather than driven away from the territory . Pencil popper being retrieved fast on the surface resembles longtom which is the favourite food of GT are often seen chased across the shallow .
As for how to work the lures , we fishermen must send the right signal so our lures are attractive to be attacked or eaten . Having the gutt feeling on which lures are to be used in one particular area is in certain condition may proved to make the difference .
One thing for sure , those who can cast accurately to the required distance is generally come out to be the winner .
