There is a big thread about RF here -
http://vapingunderground.com/threads/real-flavors-flavorings.241864/
There are also threads about hem on ECF and ELR, with ELR being the most active for RF users.
Some of my faves from them: taffy base, meringue, souffle, butter toffee, aged bourbon cream, bourbon, bread pudding, french toast, pumpkin pie, paczki, cookies and cream, deep fried cookies and cream, brownie, strawberry, orange, sugar cub, hazelnut, fruit pebbles. I like a lot (most) of the other 60+ flavors I have from them and have a laundry list of other flavors I want to order from them eventually but I am still trying to use up my non-RF stash of flavors and the RF go so far mixing at 3.5% that these 60+ flavors will likely go bad before I can vape them even with me storing them in a mini-fridge.
