Excellent read Peter, thank you.
The impact a big chub can have is quite extraordinary, they really do look the part!
A couple of years ago I returned to my "home" river on the Dorset Stour (Throop) and finally managed to get a 6-02 and then equalled my long time pb at 6-06 (a positively huge fish for the 1980's), both on the float. I've since improved that pb to 7-02, which was a bit special, even though it came on the feeder :wh, but that first one stands out as the one.
