I guess no one replied because it's kinda controversial, although this is an opinion forum...
I agree with you that a lot of the models featured are faking, as with a lot of sites. From the videos I've seen, it seemed that Sara and Chantelle were truly ticklish. Funny girls to watch. I personally liked "Like never Before" the best because of that. But, I can understand the companies positions, since:
1. A lot of people aren't into tickling
2. Very ticklish people HATE to be tickled
3. Finding very ticklish AND cute models has to be VERY hard.
Anyway, to answer your question, I haven't seen the video, but from the preview, it looked like the 2nd girl was ticklish.
If you want authentic, but not so cute ticklees, I suggest ANA. If you want the tradeoff, which is beautiful models who aren't so ticklish, I suggest RT and FM. MTP has a good mix. I personally prefer ticklishness over beauty, but that's your choice.
