Two Oceans and Comrades

I have been considering running the 2 Oceans as a prep race for the Comrades Marathon in May, but everyone I talked to who has a bit of running savvy advised against it. Some believe that as novice Comrades runner I need to be on the Comrades starting line with a fresh as possible pair legs. Running the 2 Oceans combined with all the traveling will not give me enough recovery time as the two races are only a month apart. I am a bit bummed out as I would have like to run in the Cape, will have to try and fit it into the calender for 2012!
