Hello, and welcome to the Forums.
I haven't been on Grafham for a few weeks, but we caught then on a mixture of nymphs and blobs, with lines from a floater to Di3. For recent info keep an eye on Rutland Gillies (sic) website, talk nicely to John or Ray or any of the wardens when you arrive at GW, be prepared to keep on the move and be prepared to try anything from buzzers and nymphs on a floater to lures on a Di7. Oh, and don't use thin string - these Grafham rainbows fight like nowhere else imho. Have a great time and don't forget to report back

!
Regards,
