I get 'em from Mitsuwa. They do run out regularly. I actually parboil them, drain them and dry with paper towels. Then flip them around in a skillet with a little soy or Worcestereshire miso or whatever, maybe some small shrimp or tofu cubes and green onions. Something salty-fishy tasting helps cover up any lingering scent, which to me is not very offensive, just kind of like baking soda. You can get them kind of glazed and crispy, especially the linguine.
They would be miserable substitutes for Italian pasta IMO.
