We do yellow fish on fly here in the orange river RSA, still unknown to many, Large mouth go up to 22kg and small mouth up to 11kg. we also do Barbel on fly, not my favourite they grow to big, up to 50kg, when hooked it dumps its nose behind structure and you have to drag them in. Yellow is in the stream, gives a good fight fast and powerful, caught a 8kg last month, nearly had me of the boat, spectacular jumps once hooked.
