Going through a small bout of vaper's tongue and I hear menthol helps with it, also haven't had any menthol flavors in years and I miss it. The only ones I know are popular are Slow Blow and Cush Man, but from what I can tell they are less menthol ejuice, more fruity with a small tinge of menthol. Fruity menthol would be great but i'd like it to be a little more menthol-ey than that. Bonus points if its a juice that doesn't need much or any steeping!
Wish I could help out - in my analog days I was menthol only, no lights either. After five years or so of vaping, I’ve gone ice/minty and fruits, not the sweet dessert types but blends. Only two have made my list, VaporFi’s Coco-mint Cheer (I have no idea why I like it, but it’s tasty and smooth) and The Sauce LA’s Awesometown Crisp Cool Mint Mojito which is really great.
For full on menthol, I’d have to also go with Halo’s SubZero. Just strong and true menthol. I also have heard about Miller’s and DEA.
I don’t know if you’re looking for any tobacco in your menthol, or price level, but I hear that Blacknote’s Solo is amazing. So is their commitment to quality. I’d like to try them but don’t vape tobacco flavors - they’re transparent with the lab, ingredients and the nic is sourced from one Italian grown tobacco using a cold method that takes time. I gave a kit as a special gift, they have some interesting concepts - their paper is I think 100% recycled, and they will do custom printed labels for an order - a great touch I think. I don’t care for their “anti-flavoring” comments which is totally caving in to the FDA, especially considering a tobacco based ejuice company is already out of that issue but as I said, it’s top notch and I’m nice to my friends.
I hope you find what you’re looking for.
