Yikes, how long to steep and favorite flavor. Those are some tough questions, and very subjective to individual taste. That depends a lot on what you get and what you like. Honestly, for me, the one flavor that I've found that I just have to have on hand isn't any of the vendors previously discussed, and it isn't an ADV (all day vape) for me--It's Rawr Truth Serum. And Rawr (
Rawr Vapor: Home page) doesn't even have flavor strength options. So it totally runs contrary to all my previous advice.
Honestly, I don't have an ADV. I may have mentioned that I'm a flavor junkie? So I like to switch up flavors a lot. And I've tried a lot (many of them are pushed toward the back of my seriously over-stocked juice drawer). What kinds of flavors do you like, and maybe I can help steer you in a good direction?
