You would have a hard time finding two yeshivos that are any more different in my opinion. I’m guessing you’ve been to ohr shraga, as both yeshivos go there in the summer. If so, you know which rebbeim to speak to from both places. If I’m off base and you haven’t been there, I’d suggest talking to your own rebbe who knows you and would know which kind of environment you’d do best in. Perhaps there are other options you haven’t considered?
