Yes Sir.
I think the answer to most of your questions can be satisfied within the Wannabe Forums. Search the threads. Your assesment of PLENTY OF JOBS is slightly incorrect
me thinks!
In summary, the job market in mainland Europe sucks. In the UK there are jobs and a shortage.........of experianced pilots. There are openings in the UK for low houred guys\gals but for every job there is fierce competetion not just from the locals but from all the other wannabees that cant find jobs across the channel and the Canadians, Americans, Australians and Kiwis that have the right to work in the UK.
I lived in the USA and moved back to the UK thinking (like yourself) it would be easier to get a job......wrong. Its tough. Think about it this way:-
If you stay in Canada it will be difficult to get a job.
If you come to the UK it will be difficult.
If you stay in Canada and go through the North American System you will be spending less than half the amount it will cost you in JAR land.
Good luck.
