There's a competition in the States called "Carp Diem", in which you have to c&r carp using fly only. The best anglers do this with a dry fly, so I reckon what you're doing is practising for going to America and kicking ass
There is nothing wrong with catching fish that are "coarse" with a fly. It is just snobbish to think otherwise so keep at it.
The water looks superb and everyone needs a superb local water. And if nobody else fishes it due to lack of trout, it's all yours.
Loving the photos. Keep the rod out of them and you'll have a really cool set to use as a screen saver.
More than anything, enjoy it.
Oh and watch out for a bunch of chaps from up north arriving with 2 and 3 weight rods...
