There are not enough boys in Ohr Yisroel to draw general conclusions about “type” or “yeshivish” or “going off the derech”. Also, the yeshiva is trying to be something that doesn’t really exist in the yeshiva world, so it is difficult to label.
From what I have heard, the yeshiva is well-run, and both limudei kodesh and chol are on a high level. For a few reasons, I imagine this is going to continue.
First, the rosh yeshiva comes from a strong yeshivish background but has strong ideas about development of the bachurim in areas other than learning as well, including chol and middos. Conversely, the baalei batim involved in the yeshiva are accomplished in limudei chol and careers, but are strongly committed to ruchnius. The yeshiva is a product of an idea that the founders, including the rosh yeshiva and baalei batim had, to create a particular type of yeshiva. They have b’h been successful to this point, but if it does not work out, unlike some other yeshivas, they will not re-brand themselves as another kind of yeshiva so that people can maintain their shtellars.
