I fish the river Tees at Croft and there is big chub there, they has to be, only they never get caught, i know a lot of anglers who fish there and they hear of big chub. Big ones hav to be there the record wasn't that far away. When i fish it i cant get anything bigger than 2.5lb  a three pounder seems to be a push. It is heavily fished at weekends (club matches). Any tips on how to lure the larger chub? And what methods should i use?
