Do you have experience with them? Are you happy with the quality? Do you find them to be soft? thin/thick?
Do you know anything about the machshirim (2 runs) - Rabbi Sheikovitz in Italy or Rav Hillel Weinberger (Satmar dayan) in New York?
The retzuos under Rav Weinberger are the same or more than those under the Edah. I'm not aware of any halachic advantage so unless there's good reason, I'd rather stick with the Edah, as it's a strong selling point plus it's known that they're experts in retzuos and their supervision is thorough. Your thoughts?
