Reply To: chasidish / litvish yeshivas

Very difficult question as terms need to be defined
1- Scholastically speaking , almost every chassidic yeshiva uses Lithuanian style lomdus, while Rav Tzadok ztl and other chassidic masters are very popular in Lithuanian yeshiva.There are various other chassidic influences on Lithuanian yeshiva philosophy.
2-Chabad considers itself just that.
3-Rav Shraga Feivel ztl built his yeshiva, Torah Vodaas, with this kind of synthesis in mind.
