Definately Tag Teams. The only problem would be with the mentors, but like people have mentioned, just have 1 member of a tag team be the mentor. They could have matches with the mentor and 1 member of the tag team as well, whilst the other member watches and take's notes.
If done correctly and they used actual wrestlers a divas NXT could be good and out of all of them makes the most sense. I mean they could have Divas like Beth, Mickie, Melina, Michelle, Gail etc... as mentors.
divas could be great if they had actual wrestlers instead of beauty queens, don't get me wrong i love maryse and gail kim, but the beautiful people and daffney would destroy every diva cept beth
lacey van botch and velvet scream i mean sky are far superior than maria, kelly kelly etc...sure, for they are equally painful to watch
Tag Team would be good, give them Morrison and R truth as pros.
