Yes CC I have also seen a few pushing the 1m mark. One took my fly,but in my excitement I struck to hard breaking it off ggggrrrrr. Quite often they have also their tasters in attendance, which rush in and grab any morsel first, once u hook them it puts the big girl off. So your best bet is to find one off by itself feeding alone. Also I have found in large dams the very big carp prefer gravelly/shalely banks rather then the mud flats the vast herds prefer. I think they are hunting crays or shrimp in among the rocks.
