IMO, the two best chocolates are from Inawera and that'd be Chocolate and Milk Chocolate. FA's Cocoa, to me, still has that "taste" that is in their chocolate and I can't stand it at all, even when it's aged a few weeks. Inawera's Chocolate Cream comes in a strong third and tends to be a much deeper, richer (like chocolate silk pie) and heavier due to the creamier nature of the flavor.
Inawera Chocolate, Milk Chocolate and Chocolate Cream all work really well at around 8-12 drops per 10ml. I've never seen a true need to go higher as the flavor, to me, explodes with those amounts. Of course, different bottles drip different sized drops. The 8-12 drops reference is from InaweraShop.com's bottles. For ecigexpress or other resellers, you'd have to test them on your own, though I'd recommend starting at 5 drops unless they sell the bottles with the gold caps and Inawera labels (ecigexpress does not - they rebottle).
