I don’t fish the Yorkshire rivers for grayling, I stay up here on the NE ones once there’s a nip in the air. However, what goes, in the way of techniques, is the same for all our northern spate rivers, only taking into consideration the differing sizes of the rivers and the tackle required accordingly. There’s a bit on technique for Czech nymphing in
this article from a couple of years back. It’s obviously a smallish river up here in the NE, but the principles are the same.
I agree with treetrouter’s comments and he obviously knows the river. I would approach things in a similar way on the Wear, which I would think is about the same size – up here the nymphs that score best are bead head GRHE and PTN.
A couple of additional tips: look for creases in the flow and places where the current runs deep and will drag your flies/nymphs down to the bottom more effectively. You need a floating line because you detect takes by its movement, but in such spots, the end of the fly line will often be pulled down beneath the surface and you’ll need polaroids for this, esp. on a bright day. These, in my experience, are the best spots for grayling, which will stay on or near the bottom of the river. When you hit on a shoal, you can get a take every cast to start with, but after a while of running a set of nymphs through them, they will wise up and stop taking, whether or not you’ve hooked a fish, and its then best to move on.
