I'm sure that was an awesome experience. Those BK's sure are beautiful machines. I agree with you about the A-star. It doesn't seem to be too high on the list of preferable helicopters by the majority of pilot's out there. It's crashworthiness, or lack there of would be concerning too.
The AStar is a good overall helicopter in terms of multi mission, low average operating cost, and good product support. Like anything, there are missions it's good for and missions it's not necessarily optimal for. Good bird for news reporting, observation, general light utility. Not the best for what I'm doing, probably not the best for EMS in terms of interior room and weight carrying ability.
