I used to fish down there quite a bit both Grafham and Rutland. Best tactic at this time of year is a team of buzzers, include a Diawl back. Set yourself up on a good drift (drouge essential), and just keep in touch with your flies.
It can be a bit daunting at first but ask at the lodge and they will give you all the advice you will need for that day.
