Thanks so much for your help guys: I'd met the guy at the flyfishing shop on Grey Street last time I was up and he was immensely helpful - unfortunately I lost the guide book he sold me when i moved house recently.
I popped over to the Higham fishery, coz of vacinity. It was a strange day, and the fish were noticeably put off by the wind. There was a tiny spell of rain at about 1pm, and suddenly i was able to pick of 2 very hard fighting quality fish on an amber bloodworm of mine, and two dropped off - then the warm blustery wind returned and the fish stopped any activity. I was the only person I saw net a fish there the whole day - but had to leave about 4pm to get ready for work.
The fish I did hook faught very well, and were in a top condition - I would recommend the place to anyone looking for a cheeky day: and will definately be going back next trip up.
Thanks again for your advice and time.
