Copper Creek makes a pretty decent Mint blend, seems pretty punchy on the spearmint. Their creme de menthe is also quite tasty. When you get into the coolada blends with mints, things can get pretty frosty real quickly. I am not usually a menthol vaper, but there's a few blends like the P-38 or Nuport from Aroma E-
juice that I enjoy. Vapelicious makes a good Cool Vanilla Mint, but he's closed to new orders until the end of the month.
I don't think I've tried many wintergreens, if any at all. I have yet to review NLV's Cold Creek, but I will go for a blend with creme de menthe in a heartbeat. Think of those little chocolate after dinner mints with the minty centers- that flavor in there is basically creme de menthe.
Straight menthol is just a bit too much like Vick's Vapo-rub for me, especially when it's in high concentrations. I try to stick with blends that have balance, but I lean often towards the 'creme de menthe-
tobacco'/ 'mint-tobacco' lines rather than a pure, frosty menthol.
