Thanks abezzi for the info.
I have more than 800, but still more interested in namibia to be honest. I understand lower hours in namib, but since i come from a german culture, namibia just speaks to me more. I figure i'd probably also have a higher chance of getting into a twin in namibia. But my primary goal is to fulfill a long standing desire and have a few good years of adventure in africa before i get too old and only have regrets to look back on - i also have a reputation as the 'crazy uncle' to uphold (apparently its 'crazy' to go to africa, imagine that) ;-).
