ATC Groove,
Don't get disheartened yet mate. Go over and have a look for yourself, it can't hurt and your not paying for it.
You'll find that there are a couple of ATC organisations that will pay to fly you over for an interview
Additionally, I went through a conversion course with an individual from Geneva ACC, and that person struggled with the traffic just as much as I did, and this centre is busier than Geneva. Its horses for courses, don't put yourself down. Given the right training and time you'll have no problems..I've seen you work and if I can get a rating in a busy european centre, anyone can...but I would start learning your French now, don't wait until the last minute.
