There is the Beis Halevi’s Haggadah, which is pretty as Brisk as they come. There is also a sefer Me’orie Mo’adim (I think that’s what its called) with a collection of Torah from Family Soloveitchik – from the Beis Halevi, R’ Chaim, The Brisker Rav, R’ Berel and down to R’ Dovid shlit”a. It isn’t a Haggadah, but it has a lot on ????? ???.
