I could definitely point you in the oolong direction. Not the flavored ones though, because I don't drink flavored teas.
The non-flavored oolongs to try on adagio are:

These are darker, and have more complexity to enjoy:
The #40 is a Taiwanese oolong, which has a distinct flavor difference from other teas. The Wuyi ensemble is my favorite of these. Wuyi is a chinese oolong grown at high elevations in the rocky mountains, the plants drink nothing but pure mountain water.
Hope you can find the bright path of unflavored teas.
