I'm also in the "in-between" stage of 12 and 6 mg. I get some flavors in one, and some flavors in the other, and the ones I just can't go without (Boba Tea), I get in both. OK, full disclosure? I also have BT in 18, to take to work with me in an itty-bitty little 450 Spinner and T3 mini, for those days that I just know I will only be able to sneak away for a minute here and there. I also keep some 0 nic, unflavored around to thin things down, when needed.
And Mr. Mann, I also am not a fan of Cantal-Berry Ice, although Melon-Berry Frost is great. The descriptions of them are similar, but for me, MBF is the clear winner. I thought Rune tasted almost exactly like Cantal-Berry, and also didn't love that. I do really recommend Moonlight Serenade, even if you are not a fan of Ahl's peach. The mango really makes it work. A couple of other fruits I like that you may or may not have tried are Apple Berry Splash, Mango Colada, and Kiwi Sea. You said that Raspberry Sunset was not for you, but was that because of the raspberry (which can be iffy)? I like Strawberry Sunset a lot.
