Netiv has the potential to flip a guy out. Be warned. It can really depend which shiur the guy ends up in. Torat Shraga, etc are similar but I think less so.
Just saying, TALK TO PEOPLE about each yeshiva. Not just on the internet. Since each yeshiva is different and good for different kinds of kids, it’s super important. There are serious mixed reviews on some of these places.
ToMo is NOT MO. Some MO guys go there, but it’s a yeshivish place. Everyone I’ve known who’s gone has been yeshivish already, not just flipping out- similar to Mercaz, etc.
KBY, Shaalvim and Gush all have mixes of boys- as do all yeshivos. But all of them have the capability for a really serious boy to succeed and grow. Shaalvim has more of a reputation for being warm, KBY has a reputation for being serious, Gush (kind of) has a reputation for being more open-minded, though that doesn’t necessarily mean anything. I don’t know much about Maale Adumim’s Anglo population.
(Before anyone asks- my information comes from sisters of attendees, Israel coordinators at MO high schools, and a very close family member who works for one of the above schools and through whom I’ve had a pretty close view.)
