The only tea that I've enjoyed so far in my limited tea adventures was TFA's Earl Grey, which tastes mostly like Bergamont. I've heard good things about Capella's Sweet Tea and TFA's Green Tea, but I've yet to try either of them.
Just a few things to keep in mind. You'll need a handful of 1ml syringes, lots of sample bottles (I use the 10ml bottles from WizardLabs), VG, PG, and nicotine. With that alone, you can make unflavored nicotine at your level and save immense amounts of money. You jump down the rabbit hole face first when you start to include flavors. There are many vendors out there and none of them are perfect imo. Some popular ones off the top of my head would be Capellas, TFA (the flavors apprentice), Hangsen, FlavourArt, LorAnns, and FlavorWest. Visit their respective threads to get an idea of which flavoring agents people appreciate the most regarding each specific vendor.
For example, I like some of Hangsens tobaccos, some of TFA's "add-ons" (menthol, bavarian cream, etc), some FlavorWest fruits, and some Capellas sweets. Everyone is different though, and some people may hate every flavor that I love. I think you should research the threads for these vendors (Ex "The Hangsen Thread), and pick some of the flavors that most people agree are tasty. Best of luck to ya!
