Project Risk Management Tools

I am interested in seeing what people are using out there for project and risk management tools in Agile projects -- other than excel, MS Project, etc. Specifically, I am interested in hearing about people's experience with XPlanner and its relative strengths/weaknesses. Found this review. What else are people using ?

I am also waiting to see what the Agile Project Leadership Network comes up with in terms of specific tools and strategies. Their principles sound fine to me, but lets see some details, guys ! (Do you need to be a member to see everything they are discussing ?). I did see this though in their website: a comparison of CMMI and their Declaration of Interdependence.

Here is another interesting article discussing PERT, CPM and Agile Project Management..

Update: based on the comment, I also found this great set of resource on agile project management on Rally's website.
