Steve,
You will have to wait for the article mate, and I am sure there will be lots of interesting feedback. Suffice it to say it was a very close call, but in my opinion, as well as many others, it was not substantiated from the experienced trialists of the systems.
There are people on this site who will perhaps come in now, or after the launch of the article, and air their respective views from a fist hand maintenance point of view.
I didn't do it for the hell of it, I was extremely interested as a firer of both weapons systems about the history of both AI and Parker Hale anyway, but did it because it killed off a major arms manufacturer in the whole process, which was the saddest part of the whole tale!!
