You remind me of me, MDuncan.
Settled on Tasty Vapor's Cafe Macchiato exclusively for over two years. I still love the stuff. For me it's got everything: rich coffee taste, tobacco, maybe a dollop of cream, strong but mellow and not sweet. With a kick (I like to double-it down to 36 mg, or even 24 mg, with TV's Doubler, from the 48mg).
Then I accidentally discovered some new (to me) tobacco flavors when I ordered my first Stardusts (E-Turbos) from Mountain Vapor. They included three samples that were terrific! So I went on a hunt to see what else was new (especially in "tobaccos") in the past two years.
Ordered the sample pack from Halo. Couldn't stand any of them. All tasted like flavors on disinfectant. I kept reading how they had to steep. The only alternative was to throw them out.
Amazingly, after a month, they were all six vapable. Three especially, to me. One I actually like: Prime 15.
Do I like them enough to reorder in 30ml? No. Maybe the Prime 15 once the sample is gone, if I miss it.
Do I regret trying Halo? Not at all! Great packaging on the sample pack, professional site and good reputation at ECF. Sampling is the only way to find out for yourself.
Meanwhile, in addition to Cafe Macchiato, I've discovered how much I love Bacconut, Turkish and Maple Cured (all from Mountain Vapor) and Boba's Bounty (Alien Vapor), though I can't vape more than a few hits of Boba's at a time--I guess because it's 100% VG (makes me cough; feels like it's coating my lungs. Wish they made it in a PG/VG mix).
None of those juices need to steep. They're great (for me) the first time I use them, so I reorder them (except the 30ml of Boba's, which will last me a l-o-n-g time).
Good luck!
