I quit smoking and started vaping 2 weeks ago when my Halo Triton kit arrived, so I've been sampling their juices through that period. I've really found everyone's reviews here and elsewhere helpful in making juice choices, so I'll try to be thorough in mine. I've tried to list these in roughly descending order of most to least favourite. Bare in mind that I'm a new vaper, and my tastebuds haven't completely returned from 22 years of smoking.
* Note: I'm from New Zealand - we spell it 'flavour' rather than 'flavor' - it's not a bloody mistake! XD
Torque 56: People seem to love it or hate it, but it's REALLY grown on me, and it's hard to put it into words. I got a 30ml bottle of it, will definitely order it again. I've seen it described as a harsh 'unfiltered' taste, but to me it smells a little like unlit rolling tobacco from a fresh pouch, cured in honey. It has a really subtle perfume note that you sometimes get with rolled cigarettes. I can see cigar lovers enjoying this. Again, it's hard to describe, but definitely worth checking out.
Malibu: I've finished the second 12ml freebie that came with my last 2 orders, working on the bottle in the Gourmet Sampler, and have a 30ml on the way. I've enjoyed this one as well - coconut and pineapple, with a touch of menthol, which gives it a tiny bit of coolness and bite. I've never tried a Pina Colada to compare the taste. This one leaves very little scent behind in a room that others would smell, so I can vape this at work in a shared office without complaints.
Belgian Chocolate, Shamrock, Cafe Mocha: I was looking forward to trying these. They all taste fantastic - the Belgian Chocolate accurately represents the smell and taste of a halfway decent cafe-bought hot chocolate made with baking cocoa. Shamrock adds a small twist of mint, Cafe Mocha adds the mocha twist. Despite not personally liking them as a vape, you can tell straight away that they taste great - if you do enjoy chocolate flavours, check them out.
Twisted Java: I tried this for around 30 minutes not long after it arrived in the mail. Really strong taste unground coffee beans. This one doesn't do anything for me - it's quite overpowering, and I'm definitely not much of a fine coffee afficianado. I'm keen to have another try in a few weeks once it's had some time to sit, just to be fair, but I doubt I'll ever buy it.
Kringles Curse: I haven't tried this in the Triton yet, so I can't give a fair opinion. But I'm interested to try it. I've never thought of myself as a peppermint lover, but I do chew a lot of peppermint Extra gum. It has a strong smell from the bottle. It's winter here, so I'm going to keep this one at hand in case I get sick and need something to clear the airways. Kringle's Curse has plenty of passionate fans singing it's praises, so check them out if you want to know more.
I have some juices in the mail from a few different vendors: Mother's Milk from Suicide Bunny, Unicorn/Narwhal/Gummy Blood from Fuzion Vapour, and Hawk Sauce from MBV. I've only tried Halo so far, so I'm excited to see how these taste in comparison. I've also got a Tobacco Sampler coming from Halo - can't wait to see how the other tobacco flavours vape.
