BTW, I filled my wife's M3 with Heavenly's last night...a mL's worth. She came back with it this evening and said it tastes too much like nutmeg and did not care for it. Didn't say "ick", just not her thing. So she doesn't care for Heavenly, she didn't care for Gandy. But she likes my Johnson Creek. She's a newbie. I could probably spring those flavors on her again in two months and she'd have a totally different opinion. Who the frick knows?
After you said it, I started noticing the "nutty" flavor in HT myself (power of suggestion?), although it's more subtle to me than it apparently was to you. I can taste it in Vapin' Chimp now too. I suspect it's the same tobacco base. It's not an extract, so far as I know, so the "nutty" flavor is probably one of the "make it taste like tobacco" ingredients. I'm not much on nutty myself (555, ick), but this is so light (to me) I barely notice it, and didn't really till you brought it to my attention.
I guess I will just go and buy every flavor she has.
