A good, active fellowship should be able to absorb the trades of a chapter 3 city regardless of boosts. Especially since the world map move. I get many more trades accepted by neighbors than I did before being moved. If you are otherwise happy with your current FS, I would not leave just because Elvenstats says your boosts are not ideal for the FS. But if you are having trouble getting trades accepted, it might be a sign your current FS is not active enough.
If Dreamyn2's FS does not work out for you, consider House of the Rising Sun. We're not high pressure but we perform very well in tournament, spire, and fellowship adventures. And some of our larger members clean the trader of all fellowship trades daily, regardless of boosts.
