I'm a menthol lover (Camel menthols and I crush the ball for more menthol) and my favourite is Wowboy Peppermint. It's actually the only flavour I've found anywhere that I like enough to NOT smoke cigarettes. For reference, I tried the menthol sampler from here and tried a few menthol and mint flavours from local shops. I even prefer it to my Camels, actually. However, if I run out...nothing else satisfies and I buy cigarettes. I need a jug of Wowboy Peppermint, I think.
I wouldn't say it has a super strong menthol taste, but it hits your throat like a menthol cigarette. It's not overwhelmingly peppermint, either. Finishes with a hint of sweetness from the chocolate undertones...I'm absolutely obsessed. I find I enjoy a bit of sweet when I vape. The straight menthol flavours taste a wee odd to me after vaping them for a while. They go dull or it feels like vaping vapor rub or something.
