I was just talking about this yesterday with my friends. I would really love more flavored oolongs, too. The flavors come through better than they do with black tea, which can sometimes be overpowering. If anyone knows where to get flavored oolongs (most sites only have a couple and they're all the same flavor), please, please let me know.
Adagio's peach and vanilla are good, I'll try their other two soon.
