Hello Banana,
Last year was my first year fly fishing and I fished Sharpley quite a bit.
The flies that have worked well for me are, (but please remember I'm very much a beginner); Damsels, black buzzers, olive buzzers, apps bloodworms and when I've been desperate blobs and tinnies.
My best dries were CDC emergers, hoppers, daddies, sedges, grey/olive parachute, small F-flies and some small black dries that I don't know the name of...just little scruffy things.
The non-imitative patterns are usually classed as lures. These are the cat's whiskers, zonkers, fluffcats, blobs and the like.
Last summer I had some great late evenings fishing hoppers and daddies, I never caught as many as some anglers but I had a lot of fun fishing these dries.
Good luck, Ian.
