I did the JAA IR - 30 hours in the USA - 20 in the UK.
Did 25 hours C172 in the US, 5 BE76
10 FNPT II and 10 hours BE76 in the UK.
Completed in minimum time - and a first time pass.
I would recommend you complete more multi time in the US - it's worth the money and helps with the transition!
There were 3 other guys doing the programme at the same time.
The UK portion was with PTC Bournemouth, but they went under - so they stopped doing it for a while - believe they are offering it from later this year.
