y1234: I also learned in Darchei, and I can back that up. My brother once asked R’ Altusky about learning R’ Soloveitchik’s seforim on Gemara, and R’ Altusky told him to definitely learn them, as the chiddushim are amazing – and he had all the seforim in his house! My brother asked why they don’t have them in the yeshiva beis medrash, and R’ Altusky told him that since there is a difference of opinion regarding some of his hashkafos, he felt some of the younger boys in the yeshiva might take it as an endorsement of ALL his works if they had his seforim there. But he did encourage older students to learn his chiddushim.
My Rav (a close student of R’ Herschel Schachter shlita) told me a funny story. I don’t remember if it was with a relative or a close friend of his, but it was someone close.
So this person came from a family that was mostly yeshivish, and most of his siblings learned in Chareidi yeshivos. He went to YU, and received semichah there.
He once came home for a Yom Tov, and one of his siblings also came home from yeshiva in Israel. At a meal, his father asked the brother to say over a shtikel Torah. He told the YU guy, “Listen, so you can see how a REAL yeshiva guy learns!” The brother began saying it, and my Rav’s friend had to hold back his laughter – he was saying over a chiddush from R’ Soloveitchik zt”l!
When he finished, the father said, “So, you see? That was a wonderful chiddush! Do you learn things like that in your modern Yeshiva University?”
He replied by turning to his brother. “Abba is right. That was beautiful! Who did you learn it from?” The brother hemmed and hawed. “It sounds like a Soloveitchik type of chiddush. What do you think?” Again, the brother hemmed and hawed. The father asked, “Nu, where is it from?” The brother finally cracked and said it was from R’ JB Soloveitchik. The father never insulted YU again.
