Its not so much where, but what brand. I tend to buy Whiting or Metz in Grad A (Pro) or B. I also bought quite a few form Howard Hackle, an Alberta supplier, he unfortunately is no longer in business. I grew up in the days before Genetic Hackle which now makes tying more consistent and easier. Although I certainly still tie with good quality saddles which is a bit harder to use (a bit of a learning curve) but still a good bet. Whenever possible I try to see the product. Hope this helps
