I disagree. I found installing all your addon packs and stuff like that in one season of nlite causes problems. I have had so many bad installs by doing everything at once. Plus then if one addon gives an error, then you have to go through the process of tryying to figure out which addon it was cause you did everything at once. What I tend to do, is do one addon, test using VMware, make sure its a good install, then going onto the next addon. Less problems over all for me doing stuff this way in my year of experance doing this stuff. To each their own I guess.
