helinut,
Put a N Sea pilot with '000 hrs in IMC in a R22 in real IMC and see how long he lasts (not the number of engines but the stability of the aircraft).
as part of my instrument rating we did about 8 hours on a robbie and I found it easier to control than the squirrel on instruments probably because we were only doing 80 knots instead of 110 in the squirrel.
the squirrel was very difficult to control in pitch and would height bust in a second if you looked away. so I would not not neccesarily agree with your statement.

I have never been able to understand the CAA's requirement for two engines to get an instrument rating!
well isnt this all to do with simulating some emergencies in your twin i.e. single engine approaches and go-arounds, cant really simulate that to well in a single except as a IMC auto.
regards
