One of the biggest decisions you are likely to make.
I would offer just two pieces of advice at this stage.
1. Before you get carried away with your choice of FTO, obtain the initial class one medical from the CAA. Without this "tick in the box" you are going nowhere down the professional route.
2. Having successfully jumped through this initial hoop, why not at least visit the EU ones to get a better understanding of what they can offer you as an individual.
FTE will at least offer a potential of a foreign language as well.
