I fish a small stream, the River Nidd in N Yorks and thought I'd add my input to this excellent thread. I've not yet seen any comment on tackle set up, a month or so ago I was fortunate to have a day on the river with Stuart Croft and learnt a lot. Fishing with an 8' #3 wt rod I now always have a 3'6" furled leader at the end of the line and it vastly helps energy transfer and turnover. 3' of Bayer Perlon 3.2 lb (0.18") and then 3' of 2.1 lb (0.14") is all I ever use and leader control is so much easier.
As for flies, I rarely go below an 18, usually a 16. I have stuck to three dry flies this year. The first photo shows my modification of a Griffiths Gnat by adding a red tag
This has been my most successful fly this year and has never failed to catch. It was tied by Paul Procter and the details are in FF&FT
This little pink job is simply a slip of foam, coloured with a waterproof pen and a CDC hackle. A friend of mine was shown it in Italy and we have both had success with it in Yorkshire rivers.
I've put this photo in to show an excellent pair of scissors that you might be able to get for free! These are used by ophthalmic surgeons - and thrown away after one use! If you have any medical contacts.....
Hope this is all of interest.
Regards
Nidd
