This may be impossible to answer, but I was wondering which is now considered the preferable platform for an initial IR(H) rating? Obviously the 135 would cost more, but with it being the best selling light-twin in the last 10 years (apparently), and the police/air ambulance/onshore vip & off-shore wind farms using them more and more in practice (and asking for IR's these days) would it be the preferable option to the slightly less expensive 355? Having flown both yesterday the 135 has (IMO) a far superior cockpit instrumentation system, autopilot, fadec system etc for the job, and closer crossover to the 155 and other larger aircraft commonly used in the onshore/offshore roles... But is it worth the extra £££ for an initial rating?
