Thomas Coupling - I am curious along the same lines you are - it will be intresting to examine the outcome.
Makes me VERY glad I have not had to face the same situation, but some quick observations:
I do love my twins - especially for this type of work. In Oz, you would probably be limited to a twin for this operation.
Also, as mentioned in our thread on what we would wish for in a helicopter, several of us mentioned the collective mounted throttle like the 212/412 with a decent arc of travel (unlike say the 206). Here is another incident where such a throttle could be desirable.
