Hello all. Thanks for the replies, in answer to some of the questions.... yes they do grow to over 70lb, I also believe that someone (don't know who) has looked at the crossing of eggs (would like to know more myself). More info on the river the fish were caught from, it holds a very good head of Brown Trout and Grayling. A morning session using regular trout gear resulted in 20+ Browns up to 4lb and 15+ Grayling (don't know the weights)...... more photos to follow.
