Hares ear Klinkhamers and paraduns in size 12(ish) will produce as will the same in olive in sizes 12 & 14. Also with having some black klinks in a range of sizes as there are both midge & large stoneflies about.
If nymphing, a hares ear or pheasant tail in the above sizes is worth a throw and hares ear spiders, Waterhen Bloas or partridge and orange should all produce if your preference is to fish wets.
