I've caught browns in the UK, and have caught them in Germany (I was an exchange student there in the late 80's). Much different fishing, you had to PAY to fish the beats in both countries. Germany was more a "club owned" sections of rivers, if not all. I can honestly say that I could NOT tell the difference between the one's in the UK and Germany then the one's I've caught here. Only difference is that I had to pay all my fees to get to destinations, THEN pay to have a ghillie run with me (except for the few times I was able to get in touch with a club that owned the beat and was given more leeway to go by myself).

So, either way, you're good to go.
