Hi Dougie
Welcome to the forum.
The good news is that you have plenty of excellent river fishing close by. I live not too far away from Gloucester and tend to do the vast majority of my fishing on the
Monnow system and the
WUF passport beats there is a lot of excellent trout and grayling fishing available. I have never fished still waters myself but I am assured that the move is not too difficult - just a question of varying your approach a little.
The bad news is that we are coming to the end of the trout season (close of Sept) so it will be grayling only over the autumn and winter months.
In terms of set up, dependant on the size of stream I use anything from a 7ft 3wt up to an 8ft 6 for a 4wt. In terms of techniques... you could do worse than book yourself a day with a local rivers instructor - details are available on the WUF website and you will save yourself a lot of 4rse ache
I am generally happy to show newbies around but I am kind of tied up a little at the moment

But if you look at the Monnow thread in the rivers section (apart from the last months worth!) that should give you an idea of what to expect.
PM me if you want to know more.
Best
Dave
