What is the reason for connecting all of your first tier Web 2.0 sites on a linkwheel? Why not create the Web 2.0 sites separately and link back to money site without connecting them..? Wouldn't this be an obvious way to cover the footprint? For example, wouldn't it be better to create 10 seperate Web 2.0s all linking to your money site but avoid connecting them to each other? Then on each of the open Web 2.0 sites create smaller link wheels around them with articles and SB blasts to power them up?
