Ben,
A feature of the openness of Kintore is the 'switchability' of the wind which often has me using all the casts I have in my armoury (however poorly executed).
As I never seem to get a full days fishing nowadays I usually end up picking two or three of my more confident spots and fishing them thoroughly but here's a list of the places I've contacted fish with the fly (fresh and Kelts).
From the Top
1) Broads - Fresh fish last year and kelt last week - I prefer fishing from the LH Bank
2) Topstream - I always fish through this pool - never had a fish here but like the water. I almost had the rod pulled from my hand here three years ago at the tail end, but no hook up. Also I was fishing here another tail end day when a Salmon of about 16 lb came up from the depths looked at me and dissappeared again!
3) Millstream - Good fish holding water - had a fat Grilse here a few years ago on a size 10 Teal, Yellow and Silver.
4) Highbanks - no fish from here but again I like the water from LH bank.
5) Dykes or Neck of Bend - lost a nice fresh fish here last year, always worth a throw.
6) below the rapids, below the Boat Hole - 1 Kelt from here - I always give it a throw
7) Simpsons - 3 Kelts from here - difficult to fish the fly here for mortals - should be a breeze for you but now I've cracked it.
There are many other locations where Kelts and Fresh fish are seen every year but I find these hard to fish the fly due to speed of flow, depth, etc.
Hope this is of interest.
