Whichever school you go with, I strongly suggest you do the real-deal helicopter syllabus, rather than the transitional one. Unless you really want to learn about fixed wing, of course. To be honest, I'd probably do the ATPL route even if I wasn't planning to go IR etc, as I'm finding the material really interesting, but then I'm reliably informed that I'm a wierd cow, so my experiences may not be informative
.
I'd be happy to give you my recommendation as to which school to attend via PM, if you'd like it.
