I don't think I would call Ullman or Glaser inferior cut. They are different yes, but go ahead and prove "inferior."
I wouldn't mind an Ashby or Goodall or Landy set of sails if the exchange rate didn't suck and I wouldn't have to send it 4000 miles or more away if there is a problem- and then still who could say they were "superior" to Ullman or Glaser?
