This dry sedge pattern (tied in large sizes) was shown to me last year by a friend who swore by it, stating that when there is very little rising it has the ability to pull fish off the bottom...he wasn't wrong. Works equally well for trout and grayling and is responsible for many of my recent fish.

Variation of above for when the sedge hatching are darker
A couple of simple midge/smut patterns which can be effective when fish seem to be rising at nothing visible.
