I am currently in GB came from Canada got everything I need, but the grass is always greener elsewhere...My suggestion: Offers don't come often If they come at all so grab the opportunity and stick to it for couple of years, then you will be more employable anywhere for that matter, therefore job hunt will be a bit easier for you.
Here in England is not so great regarding the jobs with low hours. Everyone hurdles into jobs like Ryanair etc...but they forget the fact that out of 20 first officers they are hiring there is about 1000 applications (little bit less) for that position with 200 something TT pilots. So really, what are the odds of getting in? After spending $35000 for type rating, even if you are succesful in assesment, you still have to satisfactory complete the training,otherwise: bye,bye, that's just the way it is...
I'd pick Asia over UK anytime If i could(China, Thailand,Indonesia...)
