Monk solo leveling guide?

[Grayskull]

Hi guys. I've been soloing on my monk, but I'm starting to hit a road block of places to go. Right now, I'm level 21, and have been soloing in Oasis, and its been good. However, lots of things are starting to turn low green, which, combined with the general crowding in Oasis, has really caused a slowdown in XP. I looked around to see if I could find a monk soloing guide, but couldn't find anything.. WIth that in mind, I'm wondering if any of you can point me in the direction of a good monk soloing guide? Or, if not that, then maybe suggest a few spots on where I could solo from level ~21-30 or so.

If it matters, this toon is a human monk with FBSS and Quivering Staff, so DPS is pretty good.
