One point which hasn't been mentioned yet on this thread is that the NMH is meant to replace three other niche military fleets as well as the Puma. The other three types are all much smaller, so the 225 looks rather big as a solution. As one example, having 225s in Cyprus would bring to mind the old adage about sledgehammers and nuts. For this reason as well as others, I suspect a smaller type will be selected.
