Ok I'm currently 93 GSM and I've been doing the garden ponds and carbuncle chromometers. I can verify that both give out fieldcraft 3's. Sometimes in bundles of 2. Ive noticed that the Garden Ponds are the best way to go if you are in a pinch and have access to mining and house merchants. The Kobold mart is great for mats as well. Hope this helps and I'll post a screenshot the next time I do it.
