Personally I would love to find out that Jill & Thomas won. That they were actually on that flight (or an earlier one though that is highly doubtful with the type of planning done on the last half dozen final legs).
I have no problem with any of the final three teams winning as all have had strong legs, all have had poor legs, and all seem to be actually racing...through this season.
But I have never really wanted a female team to win if their was a feeling like casting was trying to help enable it, by either casting softer competition, or by casting more. Just like season four seemed to just hand over the race to one of the many male teams cast.
As for casting soft the productions type of male casting has changed dramatically over the years, even going so far in all stars as not considering them for spots (I still get upset about that). Seasons 11, 12, 13, and 14 featured no fit athletic young male teams. Though with season 15 you had Sam and Dan and while Flight Time is over 30 they certainly were physically strong so lets count them as well and 16 had Jet & Cord (again I think one was in their 30's or 30) but they were physically fit so I would count them. And of course 17 back to no fit young athletic male teams.
Of course with the race a good chuck is luck and teams that on paper should do well can do terrible.
I would rather have just seen a female team win against strong male teams, as well as fit young couple teams. Thats probably my only real complaint.
