Im not sure what your getting at with that remark..
Theres plenty of facilities in the Uk and if you go galloping of to the states to do your instrument rating you'll need to do a conversion to use it in the Uk, so whats the point?!
No I don't have an IR, I did about 15hrs instrument training in the US for my IMC rating. The availability of approaches in the US is much better than the UK which makes it ideal for training...and they are free.
True if you want a JAA IR then it has to be done in the UK but there are a lot of people flying N reg with FAA IRs in the UK so your comment that you need to convert the IR isn't completely accurate.
All I was saying was that licencing issues aside as a pure training enviroment for instrument flying the US is better.
