I was thinking more like men and women were divided randomly into two groups of 6 and they compete in 4 Rounds something like:Round 1: Andrea, Corinne, Eddie, Erik, Malcolm and Sherri
3 fastest move on to Round 3
Round 2: Brenda, Cochran, Dawn, Michael, Phillip and Reynold
3 fastest move on to Round 3
Round 3: 3 Winners from Round 1 and 3 Winners from Round 2
3 fastest move on to Final Round 4
Round 4: 3 Winners from Round 3 compete for Individual Immunity Necklace
Note: Strange not to have 2 Immunity Necklaces (male and female) as they have in the recent seasons.
