My faves:
1.
US Menthol from DFWVapor. The description states, "Pure menthol nothing less , nothing more." I don't quite agree with it. I don't really know how to explain it...I just like it. Make that "love it". If I could only have a single juice...this is it.
2.
No Nic Menthol from alvinecigs. I know you want nicotine...but this stuff is awesome. THIS stuff is "pure menthol". The funny thing about menthol, IMO, you can mix it with anything and make a menthol smoker happy (really...you've got to try menthol'd RY4!). For the price, this stuff is worth keeping around to add to other "stuff". My "all day vape" is this no nic stuff mixed with the dfwvapor menthol (...but I've run out
).
3.
Smooth from blue mist vaping. This stuff has a nice flavor. Very, VERY nice flavor. The sample I ordered was a bit more nic than I'm used to, so I had to lay off it. This juice in 16mg nic hit me harder than the dfwvapor stuff does @ 24mg (if that makes any sense!) I'll be ordering a lower nic, 128ml bottle from them sooner or later...its different enough from my normal juice...but still a nice menthol.
For what its worth, I'm really impressed with the juices from bluemist. The Vanilla Mint, while not "menthol", is stupid good. I have a sample of their hypermint, but haven't tried it in a clean atomizer yet.
I've tried "menthol smooth" from liberty flights...I'll not order that again. It was usable after I mixed it with my no-nic stuff (#2 above), but alone? nah.
