Thank you for all your answers so far, I think the one or other will help me with my thinking and decision process.
Regarding my licence:
I did my training in Switzerland and got my licence there acc. JAR-FCL rules (long range should be included as far as I know) and transferred it to Germany when I started with my current employer, so it shouldn't be too hard to transfer it again.
And I'm sorry to tell you that my girlfriend is a German who decided to live in Scotland. Therefore I have no closer experience with Scottish girls so far.
Regards
Georg
