Im just basing this on how modelesque the cast was, not like age and stuff like that.
Cycle 6, definitely. They were all pretty tall, and I think for the most part, they were strong models all around. I could've seen any of them wining, except for Wendy, and she was eliminated second, so that's good.
Cycle 10. I think they are really modelesque. I dont know why, but everytime I think of cycle 10's modelesque-ness (lol) I think of Katazrzyna. She's so high fashion. She has long legs and a small torso, she's the perfect size for modeling, she has a gorgeous face, nice cheek bones, a great walk, and decent photos. It's funny that she's not even my favorite and I'm talking about her like this. Anywho, besides her, we have arguably the best plus-size model ever, an Iman look-a-like, and another one of those girls who has never taken a bad photo.
I think cycle 5 had a lot of strong models, but I dont know. I just wouldnt say the whole cast is great.
