I really have little idea, but if you're interested Tom at DonegalExpress is rating them.
Tom has everyone's favorite Nigerian, Francis Cardinal Arinze, as a favorite. But, don't jump the gun, Tom hasn't graded them all. He hasn't given us "the skinny" on Dionigi Cardinal Tettamanzi, whom I heard Kieron Wood (formerly of RTE, now of the Sunday Business Post) declare as a good bet. He's co-favorite with Arinze according to Paddy Power.
