Chromatic is a good forum style to use indeed and I'd recommend it to anyone needing advice on a style to use.. it may just be me, but I definitely prefer using a forum style that's confined to the center of the page like Chromatic, and not just one that stretches the whole way across my screen. But then again, I have been using Chromatic as my main theme for over a year now, so I'm basing that off of experience and adjustments to my eyes. :P
