My current favorite is Scorpion Blood by Mido.
The ever elusive Hawk Sauce is still favorite.
Everytime they get more in it sells out almost instantly.
I have fallen in LOVE with RY4. I have tried a DIY from a new friend I made here on the forum, as well as one from aroma e juice. So yummy!
I also love RY4, its a great ADV. So far the best I have tried is BWB's Tribeca. You should give it a try and you will not be disappointed. Its also pretty easy to DYI because its just three main flavors- tobacco, vanilla, and caramel. Vapor brothers make some good DYI for RY4 in super concentrates made with alcohol. Allusion also has some DYI concentrates but I have not tried them, I mention them because they are having a 50% off sale until the first of August. Promo code: FITYOFF
