Hi, did you ever get more info on this? I am looking for a similar answer. As350B3 or B407. I have 300 hrs work annually. $2.00 per litre, tourist work. I've heard people say they would take 10 snags on a 407 before 1 on the Airbus (relating to spares reliability and cost on the Airbus). Tourist pax do seem to prefer the open Airbus forward facing seats though.
I cant make up my mind.
