BS and MR are very growing type places, with a lot of work but not what i would consider ‘yeshivish’.
I would say the two yeshivish places in Israel are more Tiferes and Hadar, Tiferes being more chilled in a sense of hard work, but still a lot of growing goes on.
MR and BS are very similar; I would say both fit your description, aside from the ‘yeshivish’ part. They are BY, and have BY girls that go, but they are not Yeshivish…
