Korroloka Tunnel always worked for me. Sure, there's not that many bogys to choose from (9-10?) but it's a great place to farm, AFK, farm, AFK for a bit. As an added bonus, you could wind up spawning the NM (Dame Blanche) who's still surprisingly profitable if you're lucky with the drops.
This is the best Advice, in my opinion.
You get Revival Tree Roots, Cotton Cloth, and from Dame Blanche up to 4 Sarcenet Cloths (10kish each). This is by far my favorite place to piddle farm (Giddeus is a close second)
