of course, non can be same as R Blumenkranzts ztl, I went to his levaya, he didnt know me by name, but i felt so much hakaras hatov. what a caring father he was to anyone who contacted him.
I called once for someone who came from overseas, and needed a school. He told me: Tell Rabbi x I said she should go to his school, vekach haya. a 2 minutes conversation and it was a done deal BH. no discussion of tuition. just a word from R Blumenkranz. loved and admired by all.
R Gissinger I am told is very hard to reach, a lot of good people around, but no replacement, not the same. R Feiner is a young person, he moved from EY not too long ago, would be curios to hear more about him. His wife gave a shiur, and in my humble opinion it was too much like a morah talks to high school class, not my style at all.
