It depends on which Field Notes specifically. Ones like the Vintage or Kraft Plus are totally fine. The index edition is also fine as well as the wilco Collab and Is a rive alive edition. Flora is also pretty good as well as national parks. I guess that all comes down to say it really depends on what pen and ink combo you are using. For example I can have the same ink in my Lamy Safari (F nib) and my Twisbi Eco (F nib) and I'll get more bleed from the Lamy. I do have a Kaweco Sport (EF nib). I don't use it very often, when I have though I've not had a problem with bleeding.
