I haven't tried Halo's Menthol Ice yet. But have heard VERY many suggestions for it. But, being an ex Kool, Newport, generic full flavor menthol, (whatever I could get cheapest). I have found a really, really good juice that comes close.
freedomsmokeusa.com, get pall mall, 36mg, and ask them to add menthol
and,
I'm finding that one that I got somewhere along my journey that I've ordered more of with a different vg/pg mix, is Backwoods Brew Menthol Tobacco
A tip from someone that lived it... I was searching and searching for the perfect menthol with the perfect throat hit. I got a lot of good menthols... but, now that I'm off of analogs, I'm finding that the menthol portion is just not as important for me.
I'm finding that I need a good tobacco hit (pall mall is best... and I'm still "testing" backwoods menthol tobacco), is more important... with a "heavy hint" of menthol.
These are closest to Newport, Kool, etc... to me.
Good luck!
