Is this the Dane before or after Congleton? I fish the Eaton fly fishers stretch of Dane just before it flows through Congleton, not seen any Grayling there...
Supposedly, the Grayling are only to be found on the Congleton side of Havannah Weir, which is why the EA refuse to let Eaton Flyfishers stock their stretch of the Dane with Grayling.
I've also had some cracking Grayling from the Dane on maggots around Holmes Chapel. I've never had 2 lb fish, but certainly had them to around the 1 lb+ mark.
I'm currently a member of the Eaton Flyfishers, although I think this will be my last year. It's too expensive for what it offers and the fishing isn't really that great to be honest. The wild trout are all about 4 oz and anything over that is likely to be a stocked fish from the twice-yearly stocking.
