I think that joehunt makes a very good point or two, if I may be so bold.
You don't state your age, which does have something to do with it all because youth means flexibility.
As one who has been fortunate enough to experience, in a manner of speaking, both routes, I'd say go for the bush every time. You will enjoy it and you really fly which is perhaps more than so many of the computer operators one finds in the cockpit today have ever done. There is always South Africa too which, for all its sins is a great deal more congenial a place to live and fly than England and its grey monotony.
But be warned!
Africa is a dangerous place for the white man. Once you experience the dark continent you may never wish to leave it. There is something about the place which bubbles the blood. Perhaps you should read some of Rider Haggard's novels.
Good luck in your ventures and if you do go down south, make sure you pick up some of the local language as fast as you can. It'll serve you in very good stead.
Hamba Gashle!
(As they say in Zulu.)
