Sorry for the delayed response. I've enjoyed them all, but my absolute favorites are the following. A lot of them have some kind of citrus-ness to them in varying degrees, which I like:
A Quiet Morning: This one's my favorite. The name is appropriate. It tastes mildly citrusy from the passion fruit, with a little tea flavor as well. It's not overpowering. Could be my new daily driver.
Afternoon Tea: Very pleasant tea flavor. Has a bit of creaminess to it.
He Said, She Said: Tough to describe, but I really love this one.
Orange Makes Me Creamsicle: Best orange creamsicle flavor I've tried from any vendor.
I liked the rest, too, but those were my favorites. I'd recommend a sample pack with the above flavors, plus Frost Blossom. It looks like that one is only available in sample packs at the moment, and that was another really good one.
