I can't waste anymore time experimenting with the niche game only to be tossed aside whenever Google feels like changing the rules. I like the idea of authority sites and I think I can handle running three of them. I'd like to stay within the "magic" niche of money, sex, and health. One for each site. I would think on the money site I could sell anything from alternative energy products to game hacks. I have a decent web deals domain. I just can't handle running more than that on top of all my other stuff, but I think by putting an hour into each a day I could get them moving up the food chain within a couple months. How many authority domains do you have?
