Bow 5,
I have just finished the ab initio course at WMU, cannot recommend it highly enough. Awesome experience, great flying, great equipment and good instruction. Most of the course past all their JAA theory first time. You return to England after 12 months to do your IR at Bristol Flying centre, again no complaints with them, the changes between flying in the US and UK are not very dramatic as you are well prepared in the US.
Overall if WMU goes ahead with the new JAA course they are advertising in flight then you should have no worries. I now have a great year of memories!
