I second the Rose v2, and will add the Orchid v4. I have both, and both deliver roughly similar flavour, tho the Orchid is airer and produces better vapour. You have to wick more carefully on the Orchid due to the tight build deck, but I've run 80/20 juices without issue.
Have you considered the Big Dripper? Because it's essentially a dripper with a tank on top, you get dripper quality flavour and it will hold 5ml when filled correctly. It also produces massive amounts of vapour, and has all but replaced the tanks in my collection. I'm just waiting for them to come out with one that has a center glass section so you can see how much fluid you have left
