We have a set of Ari's in our studio at work. We use them mostly for video production, but I have used them on ocasion. The lights get so hot that everyone in the room (a huge studio) ends up sweating. I find that I can get the same look with my strobes, and the sessions go a lot smoother due to the comfort level going way up this way.
There is a book on hollywood portraits, I'm not sure if you have seen it or not, it has the poses and rough layouts for the lighting. Remember, a lot of that look is due to using large format film and expert retouching with lead pencils.
