I like vanilla and coffee flavours. Some of my favourites are Northern Lights Vanilla 54 Blend from Vapour Juice (think that's the only place you can get it). Decadent Vapours Doppio Espresso (caffeinated and I think that makes a good coffee, same as the decaf you drink never tastes right to me), some RY4s (they atre classed as tobacco and there's a huge variation, they are tobacco, caramel, vanilla and cocoa basicly). I find some harsh... or strong TH, depending on point of view. My favourites are Decadent Vapours DV4 which has a popcorn taste and Ace Vapers AV4, which I think has a touch of el toro style steeped tobacco plus popcorn. Both of these are smooth and Ace Vapers is organic so needs steeping.
I always have some DV Very Vanilla handy, it tames the fiery taste of some RY4s especially.
Have you ever tried T-Juice Vamp Vape? It's a caremalised coconut and another favourite of mine. I'm afraid I've yet to find a convincing chocolate but maybe I'm too fussy. I like my flavours to be what they say on the tin and I've never found an artificial chocolate flavour I want to eat, never mind vape. Unfortunately nobody has managed to produce an organic chocolate yet. Maybe when I start making some for myself I'll have a go as I love chocolate but I think the melting point is too low and it would just gunk the coil.
