Shorting CDO's

[jws43yale]

I have reason to believe that many of the CDO's that are still in operation will be hurt by the subprime woes in the upcoming months. I have information from a hedge fund superstart that the markets will be in for more hurt as these things begin to unravel. Being young and willing to take high risk, I am looking for the most effective ways of shorting or taking advantage of this downside risk. But, I do not know much about bonds or these collateral backed securities. Any ideas woudl be greatly appreciated.
