Your based in London?
And the Taff you say is the closest river to you?
So far I was chasing trout with a spinning rod and Taff was the closest river that I could find allowing this method. Actually it's a bit of a hassle for me to get there as it takes me 6 h from home to the bank of the river using public transport. Switching to fly should open more rivers closer to me. I hope.
